Question

Use the graph of the function g(x) to answer the questions A) estimate g(1)g(1)=B) estimate g(-3)g(-3)=C) estimate x such that g(x)=1D) estimate the vertical and horizontal intercept for g(x) (if an awnser does not exist enter DNEvertical intercept (x y)horizontal intercept (x y)

Answer 1

Part A

When x=1, the value of g(x)=-8

Therefore:

$g(1)=-8$

Part B

When x=-3, the value of g(x)=4

Therefore:

$g(-3)=4$

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).
