please help me
The graphs of f(x) and g(x) are shown below:
graph of function f of x open upward and has its vertex at negative 7, 0. Graph of function g of x opens upward and has its vertex at negative 9, 0.
If f(x) = (x + 7)2, which of the following is g(x) based on the translation?

Best ResponseYou've already chosen the best response.1hint: the graph of f(x), can be obtained from the graph of g(x), making a traslation by 2 units to right

Best ResponseYou've already chosen the best response.1or, vice versa, the graph of g(x), can be obtained from the graph of f(x), making a traslation by2 units to left

Best ResponseYou've already chosen the best response.1the last condition, can be expressed by this formula: \[\Large g\left( x \right) = f\left( {x + 2} \right)\]

Best ResponseYou've already chosen the best response.0If f(x) = (x + 7)2, which of the following is g(x) based on the translation? g(x) = (x + 9)2 g(x) = (x + 5)2 g(x) = (x − 9)2 g(x) = (x − 5)2 theres are the choice they gave me

Best ResponseYou've already chosen the best response.1in other words, you have to replace x, with x+2 into the expression of f(x), namely: \[\Large g\left( x \right) = f\left( {x + 2} \right) = {\left( {x + 2 + 7} \right)^2} = ...\]

Best ResponseYou've already chosen the best response.1your function is a parabola, right?

Michele_Laino

Best ResponseYou've already chosen the best response.1the equation of the axis of your parabola, is: \[\Large x =  \frac{{12}}{{2 \cdot 3}} = ...\]

Michele_Laino

Best ResponseYou've already chosen the best response.1which is the xcoordinate of the vertex. please complete: \[\Large x =  \frac{{12}}{{2 \cdot 3}} = ...?\]

Michele_Laino

Best ResponseYou've already chosen the best response.1correct! the equation of the axis of your parabola, is x=2, furthermore, the xcoordinate of the vertex of your parabola, is also x=2

Best ResponseYou've already chosen the best response.0so the answer would be graph a because its the only one with negative 2 aas the x coordinate

Best ResponseYou've already chosen the best response.1the ycoordinate of your parabola is: \[\Large y = \frac{{4ac  {b^2}}}{{4a}}\] where a=3, b=12, and c=14

Best ResponseYou've already chosen the best response.1oops..it is the ycoordinate of the vertex of your parabola

Michele_Laino

Best ResponseYou've already chosen the best response.1so after a substitution, we get: \[\Large y = \frac{{4ac  {b^2}}}{{4a}} = \frac{{4 \cdot 3 \cdot 14  {{12}^2}}}{{4 \cdot 3}} = ...?\] please complete

Best ResponseYou've already chosen the best response.1\[\large y = \frac{{4ac  {b^2}}}{{4a}} = \frac{{4 \cdot 3 \cdot 14  {{12}^2}}}{{4 \cdot 3}} = \frac{{168  144}}{{12}} = ...?\]

Best ResponseYou've already chosen the best response.0yes that what i got 168  144 i did it wrong its positive 2 but i used thos step

Best ResponseYou've already chosen the best response.0k can you help me with this 1 Which of the following represents the factored form of f(x) = x3 − 64x?

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.1first step: we can factor out x, so we can write this: \[\Large {x^3}  64x = x\left( {{x^2}  64} \right)\]

Michele_Laino

Best ResponseYou've already chosen the best response.1subsequently, we can use this algebraic identity: \[\Large {A^2}  {B^2} = \left( {A  B} \right)\left( {A + B} \right)\] where A=x, and B= 8

Best ResponseYou've already chosen the best response.0we have to foil this right if so can you show me how i would set it up?

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.1no, it is not necessary to apply the foil method, since we have to apply that standard identity

Michele_Laino

Best ResponseYou've already chosen the best response.1you should get this: \[\Large {x^2}  64 = \left( {x  8} \right)\left( {x + 8} \right)\]

anonymous

Best ResponseYou've already chosen the best response.0theses are the choices f(x) = x(x + 8)(x − 8) f(x) = (x − 8)(x + 8) f(x) = x(x − 8)2 f(x) = x(x2 − 8)

Michele_Laino

Best ResponseYou've already chosen the best response.1so, the complete factorization, is: \[\Large {x^3}  64x = x\left( {{x^2}  64} \right) = x\left( {x  8} \right)\left( {x + 8} \right)\]
