Question

F(x)=4-3x/x Найти f(-1)

Answer 1

$\displaystyle f(x)=\frac{4-3x}{x}\\\\f(-1)=\frac{4-3\cdot (-1)}{-1}=-\frac{4+3}1=\boxed{-7}$

Answer 2

To find the value of f(-1) for the function f(x) = (4 - 3x) / x, simply substitute x with -1 in the expression:

f(-1) = (4 - 3*(-1)) / (-1)

Now, evaluate the expression inside the brackets first:

= (4 + 3) / (-1)

= 7 / (-1)

The answer is -7. Therefore, f(-1) = -7.
