Which function represents the graph y=3(1/2)^x

function a

function b

function c

function d

I dont really know how to pick the function since there is no x or y value. Although for any equation plug in the value you have to get the value you need

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
