Question

Which is the graph of f(x) = (x - 1)(x + 4)?

Answer 1

Answer:

Its the last option. On the bottom.

Step-by-step explanation:

You need to Solve for x to find the zeroes of the equation.

x-1=0 So one x is at 1.

x+4=0 So the other x is at -4.

This graph is also not negative so it does not get flipped across the x-axis

Answer 2

Answer:

Step-by-step explanation:

f(x) = (x - 1)(x + 4)

x²+3x-4

a is positive , so the parabola upward

vertex=(-3/2,-25/4)
