How do you find the range of a function.

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

Sum is 17 and their difference is 3

Daryl factors the polynomial p(x)=x3+x2−26x+24 to rewrite it as p(x)=(x+6)(x−4)(x−1). which equations must be true? there may be more than one correct answer. select all correct answers. p(1)=0 p(−4)=0 p(−1)=0 p(6)=0 p(4)=0 p(−6)=0
