Polynomial Functions. Please show work

4. a. Without using technology, sketch the graphs for each function provided and state the following for each: . end behaviour (write these something like Q2->4, don't use infinity statement) . y-intercept . X-intercept(s) . multiplicity of each factor Be sure to justify your answers mathematically. i. 3 marks f(x) = (X+2)(x-1)^2 ii. 3 marks g(x) = -a (x + 2)^3 (X-1) ili. 4 marks h(x) = (x - a)(x - b)(x+c)", where a>0, b>0, and c>0
