Question

need help with the multiple choice #3 and #4. I’m in algebra 1 and this unit is Solving Equations Graphically.

Answer 1

#3: 4

#4: 1

Explanation:

To figure out #3, you must draw a vertical line across y = 4. Note that f(x) is the same as y. The positive x-coordinate the line intersects is approximately 7.5. Hence, 4 is the answer.

To figure out #4, you must locate the x-coordinates of all the points on the x-axis. They are -6, 2, 7. Therefore, 1 is the answer.

Hopefully this helps
