Find ( -1), h(0), and h(4) for the following function

h(x)=9x^2-4

h(-1) =

h(0) =

h(4) =

simplify answer

The answers are...

h(-1) = 5

h(0) = -4

h(4) = 140

Step-by-step explanation:

In order to solve each of these, simply input the value of x into the equation.

h(x) = 9x^2 - 4

h(-1) = 9(-1)^2 - 4

h(-1) = 9(1) - 4

h(-1) = 9 - 4

h(-1) = 5

h(x) = 9x^2 - 4

h(0) = 9(0)^2 - 4

h(0) = 9(0) - 4

h(0) = 0 - 4

h(0) = -4

h(x) = 9x^2 - 4

h(4) = 9(4)^2 - 4

h(4) = 9(16) - 4

h(4) = 144 - 4

h(4) = 140

i used to know how to do this in 7th but i forget easily
