Compare the functions shown below: f(x)=4x-1 h(x)=cos(x+2pi)
using complete sentences, explain which function had the greatest y-intercept.

The y-intercept of g was 2 and g has the greatest y-intercept of the three functions.

Step-by-step explanation:

So the y-intercept is an ordered pair that has the x-coordinate as 0.

So you can find the y-intercept from an equation by replacing x with 0 and solving for y.

You can find the y-intercept from a graph by seeing where it crosses the y-axis which would be at (0,something).

So let's look at f.

f(x)=4x-1

The y-intercept is when x=0:

f(0)=4(0)-1

f(0)=0-1

f(0)=-1

The y-intercept of f is -1.

Let's look at g.

The y-intercept is when x=0.  Just see where it crosses the y-axis.

It crosses at 2 so the y-intercept of g is 2.

Let's look at h.

The y-intercept is when x=0:

h(0)=cos(0+2π)

h(0)=cos(2π)

h(0)=1

So the y-intercept of h is 1.

The largest of -1 , 2 , and 1 is 2.

The y-intercept of g was 2 so g has the greater y-intercept.
