Question

Choose the value for which 2/a+8 is undefined

Answer 1

If the value is:


`\sf{(2)/(a+8)}`

Then it will be undefined when the denominator is equal to 0.

So set the denominator equal to 0

a + 8 = 0
a = -8

So when


`\huge{\boxed{\bf{a=-8}}}`

then the value will be undefined.

Just a note:


`\sf{(x)/(0)=}` undefined


`\sf{(0)/(x)=0}`
