Temperature Measurements The relationship between the Celsius (°C)and Fahrenheit (°F)scales for measuring temperature is given by the equation.

F=95C+32

The relationship between the Celsius °Cand Kelvin Kscales is K=C+273. Graph the equation F=95C+32using degrees Fahrenheit on the y-axis and degrees Celsius on the x-axis. Use the techniques introduced in this section to obtain the graph showing the relationship between Kelvin and Fahrenheit temperatures.

In Problems 7–18, match each graph to one of the following functions:

A.y=x2+2B.y=-x2+2C.y=x+2D.y=-x+2E.y=(x-2)2F.y=-(x+2)2G.y=x-2H.y=-x+2I.y=2x2J.y=-2x2K.y=2xL.y=-2x
