For the linear function f(x)= 4 (a) evaluate f(-2) and f(4), (b) find the zero of f, and (c) graph f. How can the graph of f be used to determine the zero of f? (a) f(-2)= 1 (Type an integer or a simplified fraction:) f(4) = 2 (Type an integer or a simplified fraction) (b) The zero of f is 2. (Type an integer or a simplified fraction) (c) Choose the correct graph below. DA a G OD OB a Q G How can the graph of f be used to determine the zero of f? OOOO OA. Determine the zero of f by finding the x-coordinate of the paint where the line intersects the x-axis B.
