Question

Evaluate f(x)=−6x^2−5x+16 for f(−4) (1 point) step by step f(−4)=?

Answer 1

Step 1: Substitute x = −4:
f(−4) = −6(−4)^2 − 5(−4) + 16

Step 2: Compute (−4)^2 = 16:
f(−4) = −6·16 − 5(−4) + 16

Step 3: Multiply: −6·16 = −96 and −5(−4) = +20:
f(−4) = −96 + 20 + 16

Step 4: Add: 20 + 16 = 36, so −96 + 36 = −60

Answer: f(−4) = −60.
