<u> Solution-</u>
The given function is,






Therefore, at x=0, -1, 1 , f(x) will be 0 . Hence, 0, -1 ,1 are the x-intercepts.
Plotting the graph on desmos, the graph will be as in the attachment.
For this problem, here’s how you do it.
Answer:

Step-by-step explanation:
Given

Required
Determine the value of T

Multiply both sides by 2


Divide through by 6




$4 / 8 = 50 cents per pen
.5 * 5 = 2.50
.5 * 3 = 1.50
Ivan pays $2.50 and Jeff pays $1.50
You will move 1/3 of the circumference of the circle with a radius of 3m.
C=2πr so C/3 is:
d=2πr/3, we are told that the radius is 3m so:
d=2π3/3
d=2π m
d≈6.28 m (to nearest hundredth of a meter)
