Step-by-step explanation:
It is usually sufficient to look at one section of the graph to answer a question like this. Often the best choice is the section that has a solid dot at the end of the curve. Here, that is the right section.
The left end of the right section is at x=-2, so that part of the function is defined for x ≥ -2. The line to the right has a positive slope, so the coefficient of x will be positive.
Only one answer choice has a positive x-coefficient for x ≥ -2.
Answer: 3
Step-by-step explanation:
the amplitude in a sin equation y = asin(bx) + c is equal to a
in y = 3sin(9x), a =3
the amplitude is 3
