Question

question given $f(x)= -3x^{2}$, find $f(-10)$

Explanation:

Step1: Substitute x = -10

Substitute $x=-10$ into $f(x)=-3x^{2}$. So we get $f(-10)=-3\times(-10)^{2}$.

Step2: Calculate $(-10)^{2}$

$(-10)^{2}=(-10)\times(-10) = 100$.

Step3: Multiply by -3

$f(-10)=-3\times100=-300$.

Answer:

$-300$
