According to the graph, what is the value of the constant in the equation
below?
A. 12
B. 24
C. 48
D. 6

The answer to your question is C.48

The x-intercept happens when y=0 which is at x=4 f(x)=0=y so the x-intercept is at (4,0)

the y intercept happens at x=0, reading from the table f(0)=-200 so the y intercept is (0,-200)

so the second option
x-intercept = (4,0)
y-intercept = (0,-200)

is correct
