-8 - 4(x + 8) simplified

For which pair of functions is (gof)(a)=|a|-2?

Idon’t understand! use slope intercept form to solve: through: (2,5) slope= undefined

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol
