The x-intercept is defined to be the value of x when y is zero. Based on the graph of the function: f(x) = (x-4)(x+4), the x-intercepts are located at (-4, 0) and (4,0). At these points the graph intersects the x-axis. The midpoint of the x-intercepts is located at the middle of the two points. In this case, the graph shows that it is at the origin or at (0,0).

It is a cuz to be a function the x (domain) can only have one y (range) in d it is the number 2 in the 2nd and fourth set of ordered pairs in c it is 3 the first one and the 3rd in b it is -1 its the first and the last one
hope i helped you if u dont mind can i have brainlest <span />
To find A' they used the rule of multiplication, which is:
the derivative of a product of two terms is the first term times the derivative of the second term plus the second term times the derivative of the first.
To find b' they just isolated b'
|-6 1/2|, |-1|, |0|, |9|, these are simply going from smallest to largest, once you get past 0 on a number line it goes back by one, for example 0,-1,-2,-3 and so forth, don’t think of negatives like whole numbers
