Question

Which function has the most x-intercepts?

(images of functions attached below)

a. f(x)
b. g(x)
c. h(x)
d. All three functions have the same number of x-intercepts.

Answer 1

Well, here's a simple way to look at it.

Answer 2

The intercept, is where the line touches one of the lines on the coord plane. For example, the horizontal line (X) or the vertical line (Y).

Answer 3

do you have a graphing calculator by any chance?

Answer 4

So look back at your pictures and think ; Which function touches the X-Line the most. We're looking at the horizontal line, since it wants the X intercepts. If it wanted Y-intercepts, we'd be looking at the horizontal line.

Answer 5

g(x) touches the X line 4 times, whereas h(x) touches 3 times. f(x) touches the line 3 times as well.

Answer 6

So your answer would be B, g(x) .

Answer 7

You can use this calculator to do your graphing on the computer. Best of luck!
