Question

Evaluate the function ƒ(x ) = x 2 + 1 for ƒ(2).157

Answer 1

F(x) = x² + 1

f(2) = (2)² + 1 = 4 + 1 = 5

Hence, the answer is 5.

Answer 2

Subsitute 2 for x

assuming you mean f(x)=x²+1

remember order of operaions, exponents before addition

f(2)=(2)²+1
f(2)=4+1
f(2)=5


f(2)=5
answer is 5
