What is
l2x-1l=5 i need some its so hard

|2x - 1| = 5 

 Step one check the sides to see if it positive or negative.

OK the side is positive

Step two now we know positive is absolute value 

Step three now we can x it out. (the | straight line mean absolute) 

2x - 1 = 5

Then simplify

2x = 6
x = 3

Hope to help

:D

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
