PLEASE HELP ME! WILL MARK BRAINLIEST! I will report absurd and incorrect answers. Graphs of functions on the interval [−4, 4] are depicted below. For each function, find:
1) The domain
2) Zeros of a function (the values of x where the function is zero)
3) Intervals where the function is positive and intervals where it is negative

THANK YOU TO ANYONE WHO ACTUALLY HELPS!

Step-by-step explanation:

The positive regions of a function are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero). The negative regions of a function are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero)

A way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis

Finding the zero of a function means to find the point (a,0) where the graph of the function and the y-intercept intersect. To find the value of a from the point (a,0) set the function equal to zero and then solve for x. This involves using different techniques depending on the type of function that you have

use formula for the circle a=3.14
