Question

Help please (mhanifa)

answer the 3 questions based on the table.
1.What is the y intercept of the function?

2.What is the first difference?

3.Write an equation to represent the function given in the table. Remember we write linear functions in y=mx+b form!

Answer 1

1.What is the y- intercept of the function?

• The value of f(x) when x = 0
• The y-intercept is 5 as indicated in the table

2.What is the first difference?

The difference in values of consecutive f(x):

• 7 -5 = 9 - 7 = 11 - 9 = 13 - 11 = 2

This is also called the slope if the relationship is linear.

3.Write an equation to represent the function given in the table.

Based on the information above we have:

• m = 2, b = 5

The equation is:

• y = 2x + 5
