Solve a,b,c,d please

sdas [7]

For each, replace x with the number in the parenthaseses

a.
$f(2.5)=\frac{1}{2.5-2}=\frac{1}{0.5}=2$

b.
$f(1.75)=\frac{1}{1.75-2}=\frac{1}{-0.25}=-4$

c.
$f(2)=\frac{1}{2-2}=\frac{1}{0}=undefined$
division by 0 is not allowed so it is undefined at the point

d. because division by 0 is not allowed
