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
