The coordinate point A(4,5) after a dilation with scale factor of 2, centered at the origin, becomes the point O (4,5)
O (8.10)
O (6,7)
O (2, 2.5)​

x=4

step-by-step explanation:

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

if you are factoring then 4(x+3)

if you are simplifying 4x+12
