Given f(x)=4x^(2)+10 x, find f(-4) Answer:

Substitute x with -4: Substitute x with -4 in the function f(x) = 4x^2 + 10x. f(-4) = 4(-4)^2 + 10(-4)Calculate square of -4: Calculate the square of -4. (-4)^2 = 16Multiply 4 by -4 square: Multiply 4 by the square of -4. 4 * 16 = 64Multiply 10 by -4: Multiply 10 by -4. 10 * (-4) = -40Add results from Step 3 and Step 4: Add the results from Step 3 and Step 4. f(-4) = 64 - 40Calculate final value: Calculate the final value of f(-4). f(-4) = 24

Q. Given

f(x)=4 x^{2}+10 x

, find

f(-4)

\newline

Answer:

Substitute $x$ with $-4$ : Substitute $x$ with $-4$ in the function $f(x) = 4x^2 + 10x$ . $\newline$ $f(-4) = 4(-4)^2 + 10(-4)$
Calculate square of $-4$ : Calculate the square of $-4$ . $(-4)^2 = 16$
Multiply $4$ by $-4$ square: Multiply $4$ by the square of $-4$ . $4 \times 16 = 64$
Multiply $10$ by $-4$ : Multiply $10$ by $-4$ . $\newline$ $10 \times (-4) = -40$
Add results from Step $3$ and Step $4$ : Add the results from Step $3$ and Step $4$ . $f(-4) = 64 - 40$
Calculate final value: Calculate the final value of $f(-4)$ . $f(-4) = 24$
