Which of the following are true about the graph of f(x)=−4x2?
Select the TWO that apply.

the answer is A and D

when you differentiate the question you find that the maximum point is (0,0)i.e

when dy/dx is 0 values of x are 0,0

and the function shows that valies of x are real numbers.

d. vertex

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
