Question

I need help solving this ACT prep guide practice problem This problem has an additional picture of a graph that I will send you myself

Answer 1

we have the function

`f(x)=\sin ((\pi x)/(2))`

we have that

For x=0, f(x)=0

For x=1, the value of f(x) is a maximum ----> f(x)=1

For x=-1, the value of f(x) is a minimum ----> f(x)=-1

using a graphing tool

see the attached figure below
