1 3 9 10 TIME REI 25: Consider the function y = asin(bx), where a > 0 and b>0. Which change compresses the graph verticall
Lelu [443]

Making the value of 'a' smaller, but still positive, will make the graph be compressed vertically.

Let's say a = 1 is the initial value. If we update it to a = 0.5, then the graph will be half as tall as it used to be, so it's compressed by a factor of 1/0.5 = 2.

The value of b determines the period of the sinusoidal function.

Find f(6) if f(x)=x^2 divided by 3x+x
Alinara [238K]
So, if I'm understanding you correctly, f(x)=x^2 divided by 3x+x, or
f(x) = (x^2)/(3x+x)
f(6) --> plug the 6 in to all values of x --> f(6) = (6^2)/(3×6 + 6) = 36/(18+6)
= 36/24 --> both are divisible by 12, so 36/12=3 and 24/12=2, now we have the reduced (simplified) answer:
f(6) = 3/2, or 1 1/2, or 1.5

I don’t know how to solve this it’s exponents.
matrenka [14]

Answer:

9^6

Step-by-step explanation:

When dividing exponents with the same base, we subtract the exponents

a^b/ a^c = a^(b-c)

9^11/9^5 = 9^(11-5)

              = 9^6
