About this worksheet

Compare functions in different forms. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

I can compare a y-intercept, a rate, a value and an x-intercept across a table, a graph, an equation and a story.
I can compare maximums read from a graph and a table.
I can turn "18 cm every 3 weeks" into a rate and compare it with a table.

Standard: F-IF.C.9

Words to know

y-intercept (start): The output when the input is 0.

rate: The output change for 1 step of input.

maximum: The highest output the function reaches.

x-intercept: The input where the output is 0.

Common mistakes

Your child subtracted in the opposite order from the question.

Your child compared the rates when the question asked for the y-intercepts.

Your child compared where the two start instead of how fast they change.

What to say

Ask: which number does the question say comes first?

Ask: what is the y-intercept, the output at input 0?

Ask: how much does each one change for 1 more step of input?
