Answer :
Given:
[tex]f(x) = 2x^{2} +5 \sqrt{x-2} [/tex]
Asked:
f(3)
Solution:
Subtitute x with 3 in the function
[tex]f(x) = 2x^{2} +5 \sqrt{x-2} [/tex]
[tex]f(3) = 2(3)^{2} +5 \sqrt{3-2} [/tex]
Then simplify to find the value of f(3)
[tex]f(x) = 2(9) +5 \sqrt{1} [/tex]
[tex]f(x) = 18 +5[/tex]
[tex]f(x) = 23[/tex]
The final answer is 23
