Keeping in mind that 29/6 is greater than 4, is actually 4 and 5/6, so the amount we'll "add" will be a negative one.
Answer:
A) - Linear
B) - Linear
C) - Nonlinear
Step-by-step explanation:
To determine whether a function is linear or nonlinear.
The function of a straight line is given as :
where represents slope of line and
represents the y-intercept.
Any function that can be represented as a function of straight line is called a linear function otherwise it is nonlinear.
We will check the equations given for linear or nonlinear.
A)
The function is in the form and hence it is a linear function with slope
and y-intercept
.
B)
The function is in the form and hence it is a linear function with slope
and y-intercept
.
C)
On solving for
Dividing both sides by
This function cannot be represented in the form , hence it is a nonlinear function.
