Every time we increas x by 1, we also increase y by 9. This means that the slope is 9:
When you know the slope of a line and one of its points
, you can write the equation of the line using the formula
In your case, if for example we use the first point, we have
Answer:
The function h(x) is increasing on the interval (5, ∞)
Step-by-step explanation:
Since we cannot take a square root of a negative number, the domain of this function is restricted to x ≥ 5
If the domain is restricted to x ≥ 5, then the function is always increasing,
since h(x) ≥ 0
Therefore:
The function h(x) is increasing on the interval (5, ∞)
