State the helper graph that can be used to assist in graphin

State the \"helper\" graph that can be used to assist in graphing the following function: f(x) 7csc(pi x) - 3. f(x) = 7/2 cos(pi x) - 3 f(x) = 7/2 sec(pi x) - 3 f(x) = 7 sin(pi x) - 3 f(x) = 7 tan(pi x) - 3 f(x) = 7 cos(pi x) - 3 None of the above.

Solution

The reciprocal of Csc is Sin. So the helper graph is f(x) = 7 sin (pi*x)-3

So the answer is (c).
