The function f is given by f(x) = x^2 - 4x. Which statement is true about the graph of f? A. The graph has a y-intercept at (4,0).

B. The x-intercepts are at (0,0) and (4,0).

C. The graph of the function opens downward.

D. The coordinates of the vertex are (-2,4).

i think 5 miles per hour

step-by-step explanation:

- (2, -7)

- lines r and s and lines t and u must be parallel

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)
