Question

Drag the slider to explore changing the value of a in the graph of y = asin(x).

Answer 1

Answer:

Te trigonometric function sin(x) has values such:

-1 ≤ sin(x) ≤ 1

Then the minimum value is -1 and the maximum is 1.

If we have the function:

f(x) = a*sin(x)

We have that the extremal values are when sin(x) is 1 or -1.

So if a is positive, the maximum value is a and the minimum value is -a

if a is negative, the minimum value is a and th maximum value is -a.

Answer 2

Answer:

1a: -4 & 4

2a: -4 & 4

Step-by-step explanation:

When a= 4, the minimum is -4 and the maximum is 4

When a = -4, the minimum is -4 and the maximum is 4

(both of them have the same answers)
