It’s b because n equals weeks so after the first week he has given back five dollars because 5 time 1 is 5.
Parent function: y = f(x) = x^2
given function: y = g(x) = 3 (x+1)^2
=> g(x) = 3 * f(x + 1)^2
So, from the point of view of graphs, the given function, g(x), is the parent function, f(x) = x^2, shifted one unit to the left and amplified by a factor of 3.
Answer:
x = 28/5
Step-by-step explanation:
We can use proportions to solve
5x 7
------ = ---------
8 2
Using cross products
5x*2 = 7 * 8
10x = 56
Divide by 10
10x/10 = 56/10
x = 28/5
