Question

Find f[2) if f(x) = (x+ 1)^2 O9O6 O5

Answer 1

You have the following function:

f(x) = (x + 1)²

In order to determine the value of f(2) you replace the value x = 2 in the given function and make the operations, just as follow:

f(2) = (2 + 1)² simplify inside parenthesis

f(2) = (3)² 3² is the same as 3x3=9

f(2) = 9

Hence, the value of the function when x = 2 is f(2) = 9
