Answer:
Opt. C
Step-by-step explanation:
Since all the given options are lines, we will approach to solution using a line's equation.y=mx+b.
Lets start by using two random points from the table, those will be:
(x2,y2)=(4,11)
(x1,y1)+(2,5)
With those points, lets find the slope, which have the following equation:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
When evaluating we obtain: m=3
now, to find 'b' value, we need to eval any given point in the equation, we will use (4,11)
11=3*4+b, b=-1
From whee we obtain that f(x)=3x-1
