Answer:

-9 - 8x

Step-by-step explanation:

Andy multiplied incorrectly it should have been -4*2x, -4*-3

Sylvie forgot to multiply both sides she did -4*2x but forgot to do -4*-3

The correct answer should be...

-3-4(2x-3)

Which graph represents the function f(x)=(x-5)^2+3
hammer [34]

Answer:

Parabola

Step-by-step explanation:

We are given that a function

f(x)=(x-5)^2+3

The given function is an equation of parabola along y- axis.

General equation of parabola along y- axis  with vertex (h,k) is given by

(y-k)=(x-h)^2

y=(x-h)^2+k

Compare it with given equation then we get

h=5, k=3

Vertex of given parabola =(5,3)

Substitute x=0 then we get

f(0)=(0-5)^2+3=28

y-intercept of parabola is at (0,28).
