Question

helpppp

y=-2(x-4)^2+8

Answer 1

What do you need to find

Answer 2

the domain and range for the function y

Answer 3

Domain for quadratics is all real numbers

to find the range you need to identify the y coordinate of the vertex and whether the parabola opens up or down

Answer 4

yes

Answer 5

Yeah....so can you do that

Answer 6

so the domain all really number and the range is y<=8

Answer 7

is that right?

Answer 8

the parabola opens downwards, so its

\[y \le 8\]

Answer 9

yh thats what i mean
