Question

1. Find x if ƒ(x) = 0. Use the graph of f below. Assume the entire function is graphed below.

Answer 1

(a.) x = 0, x = 4
(b.) x = -2, x = 4
(c.) x = -2, x = 0
(d.) x = -3, x = 6

Answer 2

where does the graph cross the x axis?

the x axis is the horizontal axis

Answer 3

cross as in intersect or pass?

Answer 4

yes or touch

Answer 5

-2, 0 and 4, 0

Answer 6

put another way: what points are on the graph AND on the x axis at the same time

Answer 7

(-2,0) and (4,0), yes

Answer 8

you then list the x coordinates of each x-intercept

Answer 9

and you're done

Answer 10

so answer is C: -2, 0?

Answer 11

please respond

Answer 12

the points were (-2,0) and (4,0)

the X COORDINATES of each point are: -2 and 4

so x = -2 or x = 4 will make f(x) = 0 true

Answer 13

the answer is not -2, 0 because x = 0 doesn't make f(x) = 0 true

when x = 0, f(x) = 6. Notice how the point (0,6) is on the graph

Answer 14

so the answer is B: -2, 4?

Answer 15

correct
