Best ResponseYou've already chosen the best response.0the first one you can maybe think of it as intersection points for the line x + 3 and the parabola (x5)^2

Best ResponseYou've already chosen the best response.0or you can graph the parabola, and show where it crosses the x axis

Best ResponseYou've already chosen the best response.0im allowed on use the sight https://www.desmos.com/calculator to graph it will you help me so i know what to type in each box im sorry im horrible at math lol

Best ResponseYou've already chosen the best response.0graph that parabola y = f(x) and show the x values where y = f(x) = 0

Best ResponseYou've already chosen the best response.0k, for 7) graph y=x^211x+22 show the x values when y is zero (xaxis) those are the solutions

Best ResponseYou've already chosen the best response.0OR Graph y=x+3 and y = (x5)^2 and they should cross two times and have intersection points, the x values are the solutions

Best ResponseYou've already chosen the best response.0so how would i do numbers 8 and 9 now? im just confused on how to rearrange them like you did

Best ResponseYou've already chosen the best response.0y = x^4  x + 1 if it even does

Best ResponseYou've already chosen the best response.0another approach do a table with x values (common 3 to 3) calculate the corresponding y value plot the points "see" the intersection

Best ResponseYou've already chosen the best response.0i think that is what they want, as @triciaal says,, just show how many times y = f(x) froses the x axis, number of roots, just "see" it

Best ResponseYou've already chosen the best response.0but number 8 was no solution so what would be 7?

Best ResponseYou've already chosen the best response.0see where it crosses the x axis, might need the quadratic formula for a specific values

Best ResponseYou've already chosen the best response.0what would number 9 be?

Best ResponseYou've already chosen the best response.0i just need the equation so i can graph it and to determine the number of solutions for 7 8 and 9

triciaal

Best ResponseYou've already chosen the best response.0for each of the above equations you have the y's equal to graph "split" into the 2 y's and graph for example, number 9 given x^3 = 5  x means graph 1 y = x^3 and graph 2 y = 5 x when they intersect means the x values that satisfies both equations with that y value
