The calculated value of the function f(2) + 1 is 17 for f(x) = -x² +8x + 4
How to evaluate the function f(2) + 1
From the question, we have the following parameters that can be used in our computation:
The equation of the function is given as
f(x) = -x² +8x + 4
The expression f(2) means that x = 2
So, we have:
f(2) = -(2)² + 8(2) + 4
Evaluate the exponent and the product
f(2) = -4 + 16 + 4
Evaluate the sum and the difference
f(2) = 16
Add 1 to both sides
f(2) + 1 = 17
Hence, the value of the function f(2) + 1 is 17
