Question

If f(x)=2x^2+5√(x-2), complete the following statement:

f(3) = _____

Answer 1

Given:

`f(x) = 2x^(2) +5 √(x-2)`

Asked:
f(3)

Solution:
Subtitute x with 3 in the function

`f(x) = 2x^(2) +5 √(x-2)`

`f(3) = 2(3)^(2) +5 √(3-2)`

Then simplify to find the value of f(3)

`f(x) = 2(9) +5 √(1)`

`f(x) = 18 +5`

`f(x) = 23`

The final answer is 23
