Which of the functions below have exactly two distinct real zeros?

1. f(x) = -x2 + 14x – 45

II. f(x) = 4x2 + 4

III. f(x) = 2x2 + 12x + 18

IV. f(x) = 3x2 - 4x - 4

2,160 π

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

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

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

step-by-step explanation:

it would be 3 ÷by 6 because the number on each side
