Evaluate the function at the given values of the independent variable and simplify.

Question

f(x)= (3x)/(11*lxl)

 

(That's the absolute value of x)

 

f(r^8)

 

I don't understand how you get the answers after plugging in r^8 in the equation

Answer 1

Since r⁸ is never negative (because the exponent is even), its absolute value is just r⁸, so we just have 3r⁸/11r⁸ = 3/11
