Question

Show that the function given by f(x) = 3x + 17 is strictly increasing on R

Answer 1

hey!

Answer 2

find the slope of the line.
if the slope of the line>0 then it is strictly increasing
if the slope of the line<0 then is is strictly decreasing

Answer 3

@freckle how do you find the slope of the line? :( Differentiating it?

That is f'(x) = 3 so its increasing?
