Answer: The correct option is A., i.e, Slope of Function B = 2 x Slope of Function A.
Step-by-step explanation:
The given function is,

It can be written as,

It is the slope intercept form like y=mx+c, where m is the slope. On comparing the f(x) with the slope intercept form, we get the slope of f(x) is 1.
The graph of function g(x) passing through the point (-1,-3) and (2,3).
If a line passing through the points
and
, then the slope of line is,


The slope of g(x) is 2.
Since slope of f(x) is 1 and the slope of g(x) is 2, so we can say that the slope of function B is twice of slope of function A.
Slope of Function B = 2 x Slope of Function A
Therefore, the first option is correct.
