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

The answer would be - 439

Step-by-step 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
