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

$f(x) = 9x\\\\Plug\ in\ x = \frac{1}{2}\\\\f(\frac{1}{2}) = 9 \times \frac{1}{2}\\\\f(\frac{1}{2}) = 4.5$

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