Question

question given $f(x) = -4x^2 + 10x + 13$, find $f(7)$

Explanation:

Step1: Substitute $x=7$ into $f(x)$

$f(7) = -4(7)^2 + 10(7) + 13$

Step2: Calculate the squared term

$7^2=49$, so $-4(49) = -196$

Step3: Calculate the linear terms

$10(7)=70$

Step4: Sum all terms

$f(7) = -196 + 70 + 13$

Answer:

$-113$
