Question 1051149: The question comes from the parent function f(x)=l X l or absolute X.
The shift is up 3 units, a x-axis reflection, and a left shift of 2
Would the final equation be f(x)=-l x+3 l +2 or negative absolute x+3+2 it says to provide steps and I'm not sure how each individual step is set up. Does the absolute stay with the x or does it expand to absolute x+3? How would each equation be put into steps?

Question 1052179: Hello. I have been working on a 5 point graded homework or "exit card" for the past two hours or so and I just can't crack it. It asks me to create an equation where: The numerator is a quadratic equation with a x-intercept at x+2. The denominator is a cubic function. There must be one removable discontinuity at x=3, and there must be 2 infinite discontinuities at x= -1 and x= 2. How would I make this equation, please help!
