Question

A função que apresenta seu gráfico como sendo uma reta é conhecida como:

Answer 1

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 affine function 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:

 $f(x) = mx + n$

Where $m$ (the slope) and $n$ (the interception with y axis)  are different from 0.
