13: answer choice a.) f(x)=|x-3|
Explanation: the graph is shifted 3 units to the right, which is -3 because the signs are flipped in translations. You can see the -3 is grouped with “x;” therefore, it is subtracting (or shifting) from “x.”
14: vertex is (3, 0)
Explanation: the vertex is the minimum (or maximum) point on a figure. It is the lowest or highest point and is where the function “starts.”
15: Domain: (-♾️, ♾️)
Range: [3, ♾️)
Explanation: the domain is the set of all x-values that satisfy the function. All x-values can be input into the function to produce a y-value. The range is the set of all produced y-values; it is the vertical starting point to the vertical ending point.
