# What is the value of the function f(x)=7x when x=0.75?

Jun 12, 2018

$f \left(x\right) = 5.25$ at $x = 0.75$

#### Explanation:

As per the question, we have

$f \left(x\right) = 7 x$

$\therefore$ At $x = 0.75$,

$f \left(0.75\right) = 7 \left(0.75\right)$

$\therefore f \left(0.75\right) = 7 \times \frac{75}{100}$

$\therefore f \left(0.75\right) = \frac{525}{100}$

$\therefore f \left(0.75\right) = 5.25$

Hence, the value of $f \left(x\right) = 7 x$ at $x = 0.75$ is $5.25$.
