Y=x² +14x +48
y-48 = x² +14x
y-48+7² = x² +2*7*x +7²
y-48+49 = (x+7)²
y+1= (x+7)²
y=(x+7)² - 1
Vertex of the function is (-7,-1). Minimum value of this function is a vertex value , because parabola directed up.
Answer:
True
Step-by-step explanation:
If x = 2 Than (x-1)^2 = 1
If x= 0 than (x-1)^2 = 1
For a one to one function this cannot happen as there x determines f(x) but also f(x) determines x.
I am almost positive that the answer is the first one.
I believe that it would come out to become true
