In the xy-plane, the y-coordinate of the y-intercept of the graph of the function f is c. Which of the following must be equal to c ?
A
B
C
D
Correct answer: A
Explanation
Choice A is correct. A y-intercept is the point in the xy-plane where the graph of the function crosses the y-axis, which is where . It’s given that the y-coordinate of the y-intercept of the graph of function f is c. It follows that the coordinate pair representing the y-intercept must be . Therefore, c must equal .
Choices B, C, and D are incorrect because , , and would represent the y-value of the coordinate where , , and , respectively.
