Let f(x) = 2x^2 +3x-4 find f(3h) a ) 18h^2 + 9h - 4 b ) 18h^2 + 3h - 4 c ) 2h^2+9h + 14 d) 9h^2 + 9h - 4 do with this one

A

substitute x = 3h into f(x)

f(3h) = 2(3h)² + 3(3h) - 4 = (2 × 9h²) + 9h - 4 = 18h² + 9h - 4

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
