Part A
When x=1, the value of g(x)=-8
Therefore:

Part B
When x=-3, the value of g(x)=4
Therefore:

Part C
When g(x)=1
The value of x is -2 as shown by the green line above.
Part D
The graph intersects the y-axis at the point (0,-5)
Therefore, the vertical intercept (x,y)=(0, 5).
Similarly, the graph intersects the x-axis at an estimated point (-1.7,0)
Therefore, the horizontal intercept (x,y)=(-1.7, 0).
