The table represents a function.
x: -1, 2, 3, 5
y: 0, 3, 4, 6
Complete the statement by selecting from the drop-down menu. The rate of change in the function y=2x+5 is (ANSWERS: greater than, less than, or equal to) the rate of change of the function represented in the table.
Which of the answers listed above is the CORRECT answer?

Greater than. The proper function for the table is y = x + 1

Answer:

Greater than

Step-by-step explanation:

The function y=2x+5 is written in slope-intercept form, y=mx+b, where m is the slope (rate of change) and b is the y-intercept.  The slope in this function is 2.

The slope of the function in the table is given by the formula for slope:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Using the first two points, we have

m = (3-0)/(2--1) = 3/3 = 1

The rate of change is 1.  This is less than the first function, which means the rate of change of the function y=2x+5 is greater than the slope in the table.
