Question

Evaluate the function for an input value of 3. f (x) = -4x^2 – 3x – 5

Answer 1

Answer:

• -50

Step-by-step explanation:

Function given:

• f(x) = -4x² – 3x – 5

Evaluate the function for an input value of 3

Input value is x = 3, output value is:

• f(3) = -4(3²) – 3(3) – 5 = -4(9) - 9 - 5 = -36 - 14 = -50
• f(3) = -50

Answer 2

f(3)

• -4(3)²-3(3)-5
• -4(9)-9-5
• -36-14
• -50
