For what values of x is the curve y=f(x) increasing? (1 Viewer)

Hi everyone!

I have a maths question:

For what values of x is the curve y=f(x) increasing?

a) y = 7x + 4

I differentiated it to get y' = 7. I don't know what to do from there!

Thanks

always increasing

How did you work that out?

since dy/dx > 0, it is always increasing for all x
