The graph shows the percent y (in decimal form) of battery power remaining x hours after you turn on a laptop computer.
a. Write a linear function that relates y to x.
b. Interpret the slope, the x-intercept, and the y-intercept
c. After how many hours is the battery power at 75%?

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

correct answers below:

no this is a nonlinear negative
