Question

If s(x) = 2 – x2 and t(x) = 3x, which value is equivalent to (s0t)(-7)?

Answer 1

The answer would be -439

Explanation:

To find this, start by finding t(-7)

t(x) = 3x

t(-7) = 3(-7)

t(-7) = -21

Now that we have this answer, we input it into the s(x) equation.

s(x) = 2 - x^2

s(-21) = 2 - (-21)^2

s(-21) = 2 - 441

s(-21) = -439
