Question

If f(x)=2(x)^2+5sqrt(x+2) complete the following statement f(2)=

Answer 1

The value of f(2) is 18

Solution:

Given that,

$f(x) = 2x^2 + 5\sqrt{x + 2}$

We have to find f(2)

To find f(2), plug in x = 2 in given f(x) and solve to get the answer

Plug in x = 2 in f(x)

$f(2) = 2(2)^2 + 5 \sqrt{2+2}\\\\f(2) = 2 \times 4 + 5\sqrt{4}\\\\Simplify\\\\f(2) = 8 + 5 \times 2\\\\f(2) = 8 + 10\\\\f(2) = 18$

Thus the value of f(2) is 18
