Question

3.5 module 3 post-test

if \\(h(x) = x^2 - 5\\), what is \\(h(-3)\\)?

\\(h(-3) =\\)

Explanation:

Identify the function and input

Using the Definition of a Function knowledge point, we identify the given function formula and the input value to evaluate:

$$ h(x) = x^2 - 5,\quad \text{with input } x = -3 $$

Substitute the input value

Using the Evaluating Expressions and Evaluating Quadratic Expressions knowledge points, we substitute \(x = -3\) into the function expression:

$$ h(-3) = (-3)^2 - 5 $$

Simplify the expression

Using the Order of Operations and Evaluating Quadratic Expressions knowledge points:
