Answer: e. Função afim (Affine function)
Step-by-step explanation:
The question in english is a follows:
The function that is represented in a graph as a straight line is known as:
a.Exponential function
b. Quadratic function
c. Logarithmic function
d. Delta function
e. Affine function
So, the correct answer is option e, an affine function. Why?
Because an <u>affine function</u> is a polynomial function of the first degree that does not pass through the origin of coordinates in the cartesian plane, that is, through the point (0,0) when is graphed.
In fact an affine function is graphed as a straight line, because is a linear funcition in the form:
Where (the slope) and
(the interception with y axis) are different from 0.
"Increasing" and "decreasing" are references to what the y-values do when the x-values increase.
Attached is a copy of all four tables, marked with whether the y-values increased or decreased on each step (and it also shows how much that increase or decrease was.
The only table that does this is the top right table in the attachment, which is your second table.
