Answer:
Solution(s) below.
Explanation:
This question involves the concept of reading values from graph.
The first 3 questions are basically asking you to find the value of y when x is a certain value.
a) g(7) is asking to find the value of y when x = 7.
So we can see from the graph, when x = 7, y = 4.
b) g(0) is asking to find the value of y when x = 0.
So we can see from the graph, when x = 0, y = 7.
c) g(-5) is asking to find the value of y when x = -5.
So we can see from the graph, when x = -5, y = 6 (Read from the value of 5 on the left side of the graph since x is negative.)
d) This question is asking us to do the opposite compared to the other 3 questions, its asking us to find the value of x when y = 3.
So, we can see from the graph, when y = 3, x = 9.
