Question

Find f(x+2) of the function f(x)= 4x^2+2x-4 HELP ASAP PLEASE WORTH 40 POINTS

Answer 1

Answer:

Given

• f(x)= 4x²+2x-4

To find f(x + 2) substitute x with x + 2 in the given function:

f(x+2)= 4(x + 2)² + 2(x + 2) - 4

         = 4(x² + 4x + 4) + 2x + 4 - 4

         = 4x² + 16x + 16 + 2x

         = 4x² + 18x + 16

Answer 2

f(x+2)

• 4(x+2)²+2(x+2)-4
• 4(x²+4x+4)+2x-4-4
• 4x²+16x+16+2x
• 4x²+18x+16
