Best ResponseYou've already chosen the best response.0sorry i have no idea on where to start

Best ResponseYou've already chosen the best response.1nah, x=9 will return a value for f(x) THe domain is all the input values that work the range is the values f(x) takes

Best ResponseYou've already chosen the best response.1For x^2, any real value will work, right

Best ResponseYou've already chosen the best response.1THe parabola opens in the vertical direction, it gets wider and wider forever, the values for x can be any real value That is the domain

Best ResponseYou've already chosen the best response.1THe domain of f is all values for x, such that, x is an element of the reals

Best ResponseYou've already chosen the best response.0so the range would also be (infinity,infinity)

Best ResponseYou've already chosen the best response.1hmm, look at the function. x^2 is the only variable, x^2 will always be posistive or zero

Best ResponseYou've already chosen the best response.0he's referring to the domain ony thus far =) \(\large \{x\quad x\in \mathbb{R}\}\)

Best ResponseYou've already chosen the best response.1how does that affect what values f(x) can take

Best ResponseYou've already chosen the best response.1no x will be any real number, from the domain we just figured f(x) may be limited to some interval(s) sometimes, depending on the nature of the function

Best ResponseYou've already chosen the best response.1If x^2 is 0 or larger, how does that limit the values for f(x) ?

Best ResponseYou've already chosen the best response.1something squared will be positive, (1)^2 = 1 * 1 = +1

Best ResponseYou've already chosen the best response.1To graph this parabola, you probably will figure the vertex point, and the + on the ax^2 term means it opens toward the +y direction

Best ResponseYou've already chosen the best response.0right I got the graph

Best ResponseYou've already chosen the best response.1if x^2 is always 0 or larger, the smallest value for f(x) is when x = 0 , and f(x) = 9, and the thing opens towards positive y. the values for f(x), THE RANGE , is then limited to y values greater than or equal to 9

Best ResponseYou've already chosen the best response.0so in interval notation would it look like (9,infinity)

DanJS

Best ResponseYou've already chosen the best response.1braket for the 9, it can be that value

DanJS
