Step-by-step explanation:
observe by inverse definition of a function
1 hour is 60 minutes. The ratio of 60 minutes to 45 minutes is 4:3 .
Answer:
B.
Step-by-step explanation:
Vertex with (2,4) means that the equation will have:
y=a(x-2)^2 + 4
Open downwards means that the a will be negative:
so: y = -a (x-2)^2 + 4
Stretched by a factor of 3 means that the a=3
So if we combine all of these, we will get the equation:
y = -3 (x-2)^2 + 4
