The temperature, in degrees Fahrenheit, of a scientific sample being warmed steadily as a function of time in seconds after the sample is up in a machine, can be represented by the equation f(x) = 2.1x + 86. A graph of this equation goes through the point (60, 212). What does that mean?

In 60 seconds, the temperature is 212 degrees.

In 212 seconds, the temperature is 60 degrees.

The temperature, in degrees Fahrenheit, of a scientific sample being warmed steadily as a function of time in seconds after the sample is up in a machine, can be represented by the equation f(x) = 2.1x + 86. What does it mean when x = 2?

In 2 seconds, the temperature is 90.2 degrees.

In 90.2 seconds, the temperature is 2 degrees.

The temperature, in degrees Fahrenheit, of a scientific sample being warmed steadily as a function of time in seconds after the sample is up in a machine, can be represented by the equation f(x) = 2.1x + 86. What are the INDEPENDENT and the DEPENDENT variables?

x is INDEPENDENT, and represents time in seconds. y is DEPENDENT, and represents temperature in degrees Fahrenheit.

x is DEPENDENT, and represents time in seconds. y is INDEPENDENT, and represents temperature in degrees Fahrenheit.

y is INDEPENDENT, and represents temperature in degrees Fahrenheit. x is DEPENDENT, and represents time in seconds.

x is INDEPENDENT, and represents temperature in degrees Fahrenheit. y is DEPENDENT, and represents time in seconds.

The temperature, in degrees Fahrenheit, of a scientific sample being warmed steadily as a function of time in seconds after the sample is up in a machine, can be represented by the equation f(x) = 2.1x + 86. What does it mean when y=122?

Find the value of y when x = -2.
y=3x-4

3(-2) - 4 = -6 - 4 = -10

Find the value of f(-2).
HINT: Plug in -2 for x
f(x) = 10 - 2x

10 - 2(-2) = 10 + 4 = 14

Find the value of y when x = -2.
y= ( 3/2 ) x + 5

(3/2) (-2) + 5 = -3 + 5 = 2
