The product of the functions evaluated in x = -7 is 987
which value is equivalent to (s*t) (-7)?
To find this, we just need to find the product between the two functions evaluated in x = -7
s(x) = 2 - x²
Evaluating this in -7 we get:
s(-7) = 2 - (-7)²
= 2 - 49
= -47
For the other:
t(x) = 3x
t(-7) = 3*-7 = -21
The product gives:
(s*t) (-7) = s(-7)*t(-7) = -47*-21 = 987
