Based on the set of points in the graph, determine the equation that would match the graph. (1 point) Responses f(θ)=1.5sin(π3θ) y equals 1.5 sine left parenthesis Start Fraction pi over 3 End Fraction theta right parenthesis plus 2 f(θ)=1.5cos(π3θ) y equals 1.5 cosine left parenthesis Start Fraction pi over 3 End Fraction theta right parenthesis plus 2 f(θ)=1.5cos(3θ) y equals 1.5 cosine left parenthesis 3 theta right parenthesis plus 2 f(θ)=1.5sin(3θ)
Based on the given graph, the equation that would match the graph is:
f(θ)=1.5sin(π/3θ)
