Which graph represents the function f(x)=3x-2/x-2
Question
Answer:
ANSWERThe last graph is the correct answer
EXPLANATION
The function,
[tex]y = \frac{3x - 2}{x - 2} [/tex] is a rational function.
This rational function has a vertical asymptote
at where the denominator is zero.
That is,
[tex]x - 2 = 0[/tex]
This means that, the vertical asymptote occurs at
[tex]x = 2[/tex]
The graph also has a horizontal asymptote at,
[tex]y = \frac{3}{1} [/tex]
Thus, the horizontal asymptote occurs at
[tex]y = 3[/tex]
At x-intercept,
[tex]f(x) = 0[/tex]
This implies that,
[tex] \frac{3x - 2}{x - 2} = 0[/tex]
[tex]\Rightarrow \: 3x - 2 = 0[/tex]
[tex]3x = 2[/tex]
[tex]\Rightarrow \: x = \frac{2}{3} [/tex]
The graph cuts the x-axis at,
[tex]( \frac{2}{3} ,0)[/tex]
At y-intercept,
[tex]x = 0[/tex]
This implies that,
[tex]f(0) = \frac{3(0) - 2}{0 - 2} = \frac{ - 2}{ - 2} = 1[/tex]
The graph cuts the y-axis at,
[tex](0,1)[/tex]
The graph that satisfy all the above conditions is the last one.
