Help me find it rounded to the nearest tenth

what do you need rounded to the hundreth?

The slope of the function is 'a' for x ≥ h and '- a' for x < h.

The y-intercept is (- ah + k) for x ≥ h and (ah + k) for x < h.

Step-by-step explanation:

Given function is f(x) = a|x - h| + k.

This is an absolute value function, so we can define the function as  

f(x) = a(x - h) + k = ax - ah + k  for x - h ≥ 0 i.e. x ≥ h and

f(x) = a(h - x) + k = -ax + ah + k  for x - h < 0 i.e. x < h.

Now, both the equations are in slope-intercept form and the slope of the function is a for x ≥ h and - a for x < h.

Again, the y-intercept is (- ah + k) for x ≥ h and (ah + k) for x < h. (Answer)
