Let the function f(x) have the form f(x)=Acos(x C). To produce a graph that matches the one shown below, what must the value of A be [Solved]

y = 3 when its at a maximum
y = -3 when its at a minimum

The answer in NOT 3, it is 2! I put three and got it wrong because it said the real answer was 2.

y = 3 when its at a maximum
y = -3 when its at a minimum

A = (3 (-3)) / 2
A = (3 3) / 2
A = 6/2
A = 3

There you go

The answer in NOT 3, it is 2! I put three and got it wrong because it said the real answer was 2.

Note that A is amplitude:
Max value is 3 and min value is -3
Therefore, A is 3. Choose B.
