Question

Evaluate the function for the given values of x.

-3x+7
for x < -1
g(x) =
x²+2
for -1 5
for x>4
g(-1)=

Answer 1

g(3) = 11

g(-3) = 16

g(-1) =3

Explanation:

For g(3)

g(x)= x² +2

g(3) = 3² + 2

g(3) = 9+2

g(3) = 11

For g(-3)

g(x) = -3x + 7

g(-3) = -3(-3) + 7

g(-3) = 9 + 7

g(-3) = 16

For g(-1)

g(x) = x² + 2

g(-1) = (-1)² +2

g(-1) = 1+2

g(-1) =3
