Given f(x)=-3x^(2)-8, find f(4) Answer:

Given function substitution: We are given the function f(x) = -3x^2 - 8 and we need to find the value of f(4). This means we need to substitute x with 4 in the function and simplify. Calculation: f(4) = -3(4)^2 - 8Calculate square of 4: First, calculate the square of 4. Calculation: (4)^2 = 16Multiply by -3: Next, multiply the result by -3. Calculation: -3 * 16 = -48Subtract 8: Finally, subtract 8 from the result obtained in the previous step. Calculation: -48 - 8 = -56

Q. Given

f(x)=-3 x^{2}-8

, find

f(4)

\newline

Answer:

Given function substitution: We are given the function $f(x) = -3x^2 - 8$ and we need to find the value of $f(4)$ . This means we need to substitute $x$ with $4$ in the function and simplify. $\newline$ Calculation: $f(4) = -3(4)^2 - 8$
Calculate square of $4$ : First, calculate the square of $4$ . $\newline$ Calculation: $(4)^2 = 16$
Multiply by $-3$ : Next, multiply the result by $-3$ . $\newline$ Calculation: $-3 \times 16 = -48$
Subtract $8$ : Finally, subtract $8$ from the result obtained in the previous step. $\newline$ Calculation: $-48 - 8 = -56$
