Question

If f(x) = X over 2+8, what is f(x) when X equals 10?

Answer 1

`\boxed{\huge{\sf f(x) = 1}}`

Given:

`\sf f(x) = (x)/(2 + 8)`

To Find:

`\sf f(x) \: when \: \bold{x} = 10`

Explanation:

`\sf Evaluate \: f(x) = (x)/(2 + 8) \: where \: \bold{x} = 10 : \\ \sf \implies f(x) = (x)/(2 + 8) = (10)/(2 + 8) \\ \\ \sf 2 + 8 = 10 : \\ \sf \implies f(x) = \frac{10}{ \boxed{\sf 10}} \\ \\ \sf \frac{ \cancel{\sf 10}}{ \cancel{\sf 10}} = 1 : \\ \sf \implies f(x) = 1`

Answer 2

f(x) = x/(2+8)

x = 10

f(x) = 10/(2+8)
f(x) = 10/10
f(x) = 1
