Given f(x)=4x+5, evaluate the function for f(2).
f(2)=13
f of 2 is equal to 13
f(2)=16
f of 2 is equal to 16
f(2)=11
f of 2 is equal to 11
f(2)=21
f of 2 is equal to 21
The correct answer is f(2) = 13.
To evaluate the function, substitute 2 into the function as the input for x:
f(2) = 4(2) + 5.
Simplifying this expression, we get:
f(2) = 8 + 5 = 13.
Therefore, the value of the function f(x) at x = 2 is 13.
To evaluate the function f(x) = 4x + 5 for f(2), we need to substitute x with 2 and simplify the expression.
Step 1: Replace x with 2 in the function expression.
f(2) = 4(2) + 5
Step 2: Perform the multiplication.
f(2) = 8 + 5
Step 3: Add the numbers together.
f(2) = 13
Therefore, the value of the function f(2) is 13.
