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
