Answer:
The answer is The function is decreasing for all real values of x
where
-1<x<4.
Step-by-step explanation:
Point slope form : y-y1 = m(x-x1)
slope intercept form : m=(y-y1)/(x-x1)
standard form : Ax + By = C
just pick any random points on a graph and plug the same points into all three forms.
If (x+5) is a factor the equation will equal zero when x=-5 so
3(-5^2)+14(-5)+k=0
75-70+k=0
5+k=0
k=-5
Domain: All real numbers (-infinity, infinity)
Range: [9, -infinity)
