Question

If g(x) = x² + 1, what is the value of g(-3)?

Answer 1

Explanation:

g(x)=x^2+1

at g(-3) = (-3)^2+1

=9+1=10

Answer 2

g(-3)=10

Explanation:

We want to find what g(x), or y is, when x is equal to -3.

g(x)== x² + 1

x= -3

Substitute -3 in for x.

g(-3)=(-3)²+1

Evaluate the exponent first. -3² is equivalent to -3*-3, which is equal to 9.

g(-3)=9+1

Add 9 and 1

g(-3)=10
