Evaluate the Function f(x)=8x^2+11x at x=7

$f (x) = 8 x^{2} + 11 x$ at $x = 7$

Step 1

Replace the variable $x$ with $7$ in the expression.

$f (7) = 8 {(7)}^{2} + 11 (7)$

Step 2

Simplify the result.

Simplify each term.

Raise $7$ to the power of $2$ .

$f (7) = 8 \cdot 49 + 11 (7)$

Multiply $8$ by $49$ .

$f (7) = 392 + 11 (7)$

Multiply $11$ by $7$ .

$f (7) = 392 + 77$

Add $392$ and $77$ .

$f (7) = 469$

The final answer is $469$ .

$469$
