Question

Which values complete the function?
F(x)= (X- ) (x+ )

Answer 1

-1, 3, 4

Explanation:

Answer 2

f(x)= -1(x-3)(x+4)

First blank: -1

2nd blank: 3

3rd blank: 4

Explanation:

When the parabola is flipped upside down (opened downward) there should be a negative in front. So the first blank is -1. Also, this parabola has not been stretched or smashed, that's why the value is a 1. Again, negative, because its reflected (flipped).

The other two blanks will come from the x-intercepts. The curve crosses the x-axis at 3 and -4.

If x = 3, then

subtracting 3 from both sides

x - 3 = 0

That x-3 is the

x - blank in the problem. Fill in a 3.

If x = -4, then adding 4 to both sides,

x + 4 = 0

Likewise, this x+4 is the

x + blank

in the question. Fill in a 4.
