Answer:
The answer is
Step-by-step explanation:
[tex]f(x) = {2x}^{2} + 2x - 3[/tex]
To find f(4) , substitute the value of x that's 4 into f(x). That is for every x in f(x) replace it with 4
That's
[tex]f(4) = 2 ({4})^{2} + 2(4) - 3 \\ = 2(16) + 8 - 3 \\ = 32 + 5 \\ = 37 \: \: \: \: \: \: \: \: [/tex]
We have the final answer as
[tex]f(4) = 37 \\ [/tex]
