Worksheet: Finding y-Intercepts and Zeros Graphically

In this worksheet, we will practice using graphs to find the y-intercept and the zeros of a function.

Q1:

The diagram shows the graph of 𝑦 = 𝑓 ( 𝑥 ) . What is the solution set of the equation 𝑓 ( 𝑥 ) = 0 ?

  • A { 2 , 2 }
  • B
  • C { 2 }
  • D { 4 , 4 }
  • E { 4 }

Q2:

The diagram shows the graph of 𝑦 = 𝑓 ( 𝑥 ) . What is the solution set of the equation 𝑓 ( 𝑥 ) = 0 ?

  • A { 4 }
  • B
  • C { 1 }
  • D { 3 , 1 }
  • E { 1 }

Q3:
