Use the graph of the quadratic function f to determine the s

Use the graph of the quadratic function f to determine the solution. (a) Solve f(x) > 0. (b) Solve f(x) lessthanorequalto 0. (a) The solution to f(x) > 0 is. (b) The solution to f(x) lessthanorequalto 0 is.

Solution

(a). f(x)>0 , x belongs to (-infinity,-3) U (4,infinity).

(b). f(x)<0 , x belongs to (-3,4).

f(x)=0 , x=-3,4
