Decay

300

What does f(x) represent in an exponential function?

dependent variable or output  of the function. AKA y

400

Is this equation exponential : y=3x-2

No, this is a linear function

500

Is this growth or decay: 7(1.45)^x and by what percentage?

Growth, 45%

Linear Function

100

What is a function whose graph forms a straight line called?

A linear function

200

What is the equation of a line?

y=mx+b

300

What is the slope formula?

y₂-y₁/ x₂-x₁

400

Is this equation linear: x³ +y = -1

No, because x has an exponent other than one. 

500

What are the steps to solving a linear equation?

1) Simplify each side

2) Use -/+ properties to move the variables to one side

3) Use multiplication/division

4)Check your answer

5) Solve for the variable
