Question

Compare the functions shown below: g(x) f(x) = 4x − 1 tangent function with y intercept at 0, 2 h(x) = cos(x + 2π) Using complete sentences, explain which function has the greatest y-intercept.

Answer 1

Answer:

g(x) has the greatest y-intercept (the graph)

Step-by-step explanation:

The y-intercept for f(x) is -1, we can easily identify it at the end of the function.

The y-intercept for g(x) is 2, we can see that's where it crosses the y-axis.

The y-intercept for h(x) is 1, we can find this by substituting 0 for x in the equation.

h(0) = cos(0+2$\pi$)

h(0) = cos(2$\pi$)

h(0) = cos(360)

h(0) = 1

$\pi$ = 180 when converting degrees to radians, and you can find the cosine of 360 with a calculator.
