f(2)=11
f(2)=16
f(2)=21
f(2)=13
To evaluate the function f(2), we substitute 2 for x in the given expression:
f(2) = 4^2 + 5
f(2) = 16 + 5
f(2) = 21
Therefore, f(2) = 21.
To evaluate the function f(x)=4^x+5 for f(2), we substitute the value x=2 into the function:
f(2) = 4^2 + 5
Simplifying the expression, we get:
f(2) = 16 + 5
Therefore, f(2) = 21.
So, the correct response is:
f(2) = 21.
To evaluate the function f(x) = 4^x + 5 for f(2), you need to substitute the value x=2 into the function and solve for f(2).
Step 1: Start with the given function: f(x) = 4^x + 5.
Step 2: Substitute x=2 into the function: f(2) = 4^2 + 5.
Step 3: Simplify the expression: f(2) = 16 + 5.
Step 4: Perform the addition: f(2) = 21.
Therefore, the correct answer is f(2) = 21.
