Solution:
Given that,
[tex]f(x) = 2x^2 + 5\sqrt{x + 2}[/tex]
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)
[tex]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[/tex]
Thus the value of f(2) is 18
