Answer:
100'000'000'000'000
(trillion gaxies in the universe)
Step-by-step explanation:
10×10^10= 10(10'000'000'000)=100'000'000'000
(hundred billion stars in milky way)
100'000'000'000'000'000'000'000 (hundred sextillion stars in universe)
100'000'000'000'000'000'000'000 / 100'000'000'000= 100'000'000'000'000
(trillion gaxies in the universe)
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.
