please help me with these problems

State whether the function is a polynomial function or not. If it is, give its degree. If it is not, tell why not. 1) f(x) = - 17x3 +4x2- 9 1 ) 2) 8(x - 1)11(x+1)7 2) 3) f( x ) = x3/2. x4- 7 3 ) Use transformations of the graph of y = x4 ory = x5 to graph the function. 4) f(x ) = (x+5)5+4 -10 5 10 -10- 5) f(x) = 2 - (x- 5)+ 5 ) -10 10 HHHHHHHH HHHHHH Form a polynomial whose zeros and degree are given. Use a leading coefficient of 1. 6) Zeros: - 5, multiplicity 2; 1, multiplicity 1; degree 3 6) For the polynomial, list each real zero and its multiplicity. Determine whether the graph crosses or touches the x- axis at each x - intercept. 7) f(x) = 5(x- 2)x- 6) 7 )
