Aside from the phone number, other
categorical variables in the survey that was conducted are family size, dad's
occupation, whether mom works, and kind of pets. Remember that the categorical
variable is also known as a qualitative variable. It means that categorical
variables are mostly descriptions of something, can be an individual or group
of people or things. Although phone number is entails a numerical figure, but
it doesn’t necessarily give percents or counts, or even numbers which makes it
also a part of the categorical variable.
The mathematical functions (equations) are matched to their graph line respectively as follows:
- y = 960 - 78x: purple straight line.
- y = 8·3^x: violet line curve that slopes to the left.
- y = 960·(1/2)^x: green line curve that slopes to the right.
<h3>What is a linear function?</h3>
A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate. Mathematically, a linear function is given by this equation:
y = mx ± c.
<h3>What is an exponential function?</h3>
An exponential function can be defined as a type of mathematical function whose values are generated by a constant that is raised to the power of the argument. Mathematically, an exponential function is represented by this formula:
f(x) = keˣ
Next, we would match each of the mathematical functions (equations) to their graph line respectively as follows:
- y = 960 - 78x: purple straight line.
- y = 8·3^x: violet line curve that slopes to the left.
- y = 960·(1/2)^x: green line curve that slopes to the right.
