Question

given \\(f(x) = 5x - 4\\), evaluate.
\\(f(-4)\\)

1. - / 3 points

given \\(q(r) = r^2 - 3\\), evaluate.
\\(q(-8)\\)

Explanation:

Identify the first function and input

The first problem asks to evaluate \(f(-4)\) for the linear function:

$$f(x) = 5x - 4$$

Substitute the value into the first function

Substitute \(x = -4\) into the expression:

$$f(-4) = 5(-4) - 4$$

Simplify the first expression

Multiply and subtract to find the final value:

$$f(-4) = -20 - 4 = -24$$

Identify the second function and input

The second problem asks to evaluate \(q(-8)\) for the quadratic function:

$$q(r) = r^2 - 3$$

Substitute and simplify the second function

Substitute \(r = -8\) into the expression and evaluate:

$$q(-8) = (-8)^2 - 3 = 64 - 3 = 61$$
