Given the following function, find $h(-1)$. \[ h(x)=9 x^{2}-3 \] $h(-1)=\square$ (Simplify your answer. Type an integer or a fra

Step 1 ：Substitute -1 into the function: \(h(-1) = 9(-1)^2 - 3\)

Step 2 ：Simplify: \(h(-1) = 9(1) - 3\)

Step 3 ：Simplify further: \(h(-1) = 9 - 3\)

Step 4 ：Final answer: \(\boxed{h(-1) = 6}\)
