Evaluate f(3) for the function f(x) = 3x^2 + 2x - 5.

Sagot :

ANSWER

f(3) = 28

EXPLANATION

We have the function:

[tex]f(x)=3x^2\text{ + 2x - 5}[/tex]

To find the value of f(3), we have to replace x with 3 in the function and simplify:

[tex]\begin{gathered} f(3)=3(3)^2\text{ + 2(3) - 5} \\ f(3)\text{ = (3 }\cdot\text{ 9) + 6 - 5 = 27 + 6 - 5} \\ f(3)\text{ = }28 \end{gathered}[/tex]

That is the value of f(3).
