• 4. How can you determine if a table is a linear function or an exponential function?

$\huge\underline{\sf{\red{Answer:}}}$

• Exponential and linear refer to the type of a function by looking at the power of the independent variable.A linear function is one where the independent variable is to the power of 1.

• For example, in the linear equation y = mx+b, x is the aforementioned independent variable. The term linear comes from the plot of the function; regardless of the values of m and b, the graphed function will always be a line.

• An exponential function is one where the independent variable is to a non-trivial (not 0th or 1st) power. These are typically of the form y=a⋅bx. The term exponential comes from the use of exponentiation in the independent variable.

• An exponential graph is curved upwards, while a linear graph is a straight line. One of the most important distinctions between linear and exponential functions is how (and how quickly) they increase or decrease.

• Linear functions increase proportionally; an increase in x has a corresponding additive increase in y.

• Exponential functions, however, increase exponentially; that is, an increase in x has a corresponding multiplicative increase in y.
