Oksana is working to solve the equation fx=-3x - 10. 1. Add 1 x to both sides: 1x + 3x=-10
2. Find a common denominator: È x +

Ex = -10
3. Combine the terms:
12 x = -10
What should she do next?

Divide both sides by 7/12

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
