e. why must 5 be excluded from the domain of?

mertsj · Answer

$$f(x)=\frac{5x-2}{x-5}$$

mertsj · Answer

Is that what you meant?

lynfran · Answer

so our function is $$f(x)=\frac{ 5x-2 }{ x-5 }$$and we want to know what f(0).. so where ever we see "x" in the give function we substitute '0' so..$$f(0)=\frac{ 5(0)-2 }{ (0)-5 }$$and we simplify it to get $$f(0)=\frac{ -2 }{ -5 }$$$$f(0)=\frac{ 2 }{ 5 }$$...can u do the rest??

lynfran · Answer

u just have to follow the same procedure as above

lynfran · Answer

what u got for f(1) ...??

lynfran · Answer

$$f(1)=\frac{ 5(1)-2 }{ (1)-5 }$$
