Answer:

f(x - 4) = x^2 - 6x+ 8

Step-by-step explanation:

Given

f(x) = x^2 + 2x

Required

Find f(x - 4)

Substitute x - 4 for x

f(x - 4) = (x- 4)^2 + 2(x - 4)

Expand

f(x - 4) = x^2 - 8x + 16 + 2x - 8

Collect like terms

f(x - 4) = x^2 - 8x + 2x+ 16  - 8

f(x - 4) = x^2 - 6x+ 8

Solve the following system of equations and show all work. y = −x2 + 4 y = 2x + 1
Aneli [31]

Answer:

x=3/4,y=5/2

Step-by-step explanation:

y=-x^2+4,y=2x+1

substitute y=-x^2+4 as y  for y=2x+1

2x+1=-x^2+4, x=3/4(isolate "x")

x=3/4

substitute x=3/4 for 2x+1=-x^2+4

y=2*3/4+1

y=5/2

x=3/4, y=5/2

hope this helps!
