For second one
Vertex is (-3,0)
There is only one x intercepts
There are no numbers for this, thus you will have to use the quadratic formula.
Answer:
6.25
Step-by-step explanation:
You would multiply 2.5 by itself since you're dilating your side length.
f(x) = mx + b
m = slope = -5
f(2) = 10 = (-5)(2) + b
b = 10 + 10 = 20
Ans. m=-5, b = 20
