For the linear function $f(x)=2-\frac{1}{6} x$; (a) evaluate $f(-6)$ and $f(12)$; (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) $f(-6)=$ $\square$ (Type an integer or a simplified fraction.) $f(12)=$ $\square$ (Type an integer or a simplified fraction.) (b) The zero of $f$ is $\square$ . (Type an integer or a simplified fraction.) (c) Choose the correct graph below. A. B. c. D.
How can the graph of $f$ be used to determine the zero of $f$ ? A. Determine the zero of $f$ by finding the $y$-coordinate of the point where the line intersects the $y$-axis. B. Determine the zero of $f$ by finding the $x$-coordinate of the point where the line intersects the $y$-axis. C. Determine the zero of $f$ by finding the $y$-coordinate of the point where the line intersects the $x$-axis. D. Determine the zero of $f$ by finding the $x$-coordinate of the point where the line intersects the $x$-axis.
