Question

Evaluate f(x)=1/4x for x = –5

Answer 1

F(-5)=1/(4*-5) --> -1/20

Answer 2

Answer: $-0.25$

Step-by-step explanation:

The given function : $f(x)=\dfrac{1}{4}x$

To find the value of the given function at -5, we need to substitute the value of -5 in the given function, we get

$f(-5)=\dfrac{1}{4}\times-5\\\\\Riaghtarrow\ f(-5)=\dfrac{-5}{4}\\\\\Riaghtarrow\ f(-5)=-1\dfrac{1}{4}$

Hence, the value of  $f(x)=\dfrac{1}{4}x$ at $x =-5=-1\dfrac{1}{4}\ or \ -0.25$
