Y=f(×)=9×<br> Find f(×) when x =1/2

mojhsa [17]

<h3>f(x) is equal to 4.5 when x = 1/2</h3>

<em><u>Solution:</u></em>

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
