If the vertex of an absolute value function is (1.-2) and another point on the graph is (0,2), find a and write the function in the form of g(x)=a/x-h1+k

Which function represents the sequence? f(n)=n+3 f(n)=7n−4 f(n)=3n+7 f(n)=n+7

Answer asap! show all work! find the number of complex roots, the possible number of real roots and the possible rational roots of the polynomial function. then, solve for all roots. x^3 + 2x^2 + 3x + 6 = 0

If the average of x,y and z is 15 what is their sum
