A graph titled Average Temperature has Month on the x-axis and Temperature (degrees Fahrenheit) on the y-axis. January is 25 degrees, February is 25 degrees, March is 28 degrees, April is 45 degrees, and May is 50 degrees. A city’s average temperature over five months is shown in the graph. Which statement is NOT TRUE of the data? January and February have the same average temperature. February to March shows the greatest increase of average temperature. May’s average temperature is 50°F. March to April shows the least increase of average temperature.

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75
