Answer: f(-6) = $-\frac{12}{11}$ , f(-4) = $\frac{8}{9}$ , f(4) = $-\frac{8}{9}$ , f(6) = $\frac{12}{11}$

<u>Step-by-step explanation:</u>

(-6, f(-6)) is an x,y coordinate. They are asking what the y-value is when you plug in -6 for x.

f(x) = $\frac{2x}{x^{2}-25}$

f(-6) = $\frac{2(-6)}{(-6)^{2}-25}$

= $\frac{-12}{36-25}$

= $-\frac{12}{11}$

f(-4) = $\frac{2(-4)}{(-4)^{2}-25}$

= $\frac{-8}{16-25}$

= $\frac{-8}{-9}$

= $\frac{8}{9}$

f(4) = $\frac{2(4)}{(4)^{2}-25}$

= $\frac{8}{16-25}$

= $\frac{8}{-9}$

= $-\frac{8}{9}$

f(6) = $\frac{2(6)}{(6)^{2}-25}$

= $\frac{12}{36-25}$

= $\frac{12}{11}$
