  • this helps alot but what my piecewise function says has: |x+8| + 7

    -x - 8

    -4

    x - 7

    |x - 7| +7

    how do I solve a function for -4 with no x ?

  • @Zeldaaa000 The function value is always -4 regardless of the value for x.

  • you should be a math teacher

  • @Deannerzz I am!

  • This helped me so much. Thank you <3 But I have one question. Would it still be right if you graphed the line first, (as in y=whatever) and then put the dot there? Cuz thats how my teacher explained it. I like your way a lot better though :D

  • @puppyluv1031 Yeah, you should still get the same graph. I just like to know where the individual "parts" of the graph begin and end before I connect the dots.
