Answer:
The values of x that makes f(x) have a valid asymptote are 1 and 8
Step-by-step explanation:
Given
[tex]f(x) = \frac{9}{(x-1)(x-8)}[/tex]
Required
At what value does f(x) has a vertical asymptote
To solve this, we simply equate the denominator of f(x) to 0;
This is done as follows
[tex]{(x-1)(x-8)} = 0[/tex]
This can be split to
[tex]{(x-1) = 0 \ or\ (x-8)} = 0[/tex]
Remove brackets
[tex]x-1 = 0 \ or\ x-8 = 0[/tex]
Make x the subject of formula in both cases
[tex]x-1+1 = 0+1 \ or\ x-8+8 = 0+8[/tex]
[tex]x= 0+1 \ or\ x = 0+8[/tex]
[tex]x= 1 \ or\ x = 8[/tex]
The values of x that makes f(x) have a valid asymptote are 1 and 8
Answer:
The correct answer is 1 and 8
