Question

Y=f(×)=9×
Find f(×) when x =1/2

Answer 1

f(x) is equal to 4.5 when x = 1/2

Solution:

Given that,

`y = f(x) = 9x`

We have to find f(x) when x = 1/2

We can solve by substituting x = 1/2 in given function

`f(x) = 9x\\\\Plug\ in\ x = (1)/(2)\\\\f((1)/(2)) = 9 * (1)/(2)\\\\f((1)/(2)) = 4.5`

Thus f(x) is equal to 4.5 when x = 1/2
