Consider the equation . For each question, explain or show your reasoning.Where does the graph intersects the -axis?

Answer 1

for

y = x^2 +x = x(x+1)

x intercepts = zeros = the solutions to x(x+1) = 0 which are 0 and -1

factor your polynomial and set each factor = 0 then solve for x, that gives you all real solutions = all x intercepts
