If a graph passes the horizontal line test, but not the vertical line test, is it still a function?
nydimaria [60]

If a graph fails the vertical line test it's not a function; you can't have a single x map to two ys.

Vice versa, if the graph passes the verticle line test, it's a function.  

The horizontal line test tests for injectivity aka one-to-one-ness; it has no bearing on whether something's a function.

Solve by completing the square ( need it asap pls) <br><br> x2+18x+81=-4<br><br> -don’t send link-
Sholpan [36]

Answer:

x=2.17

Step-by-step explanation:

x^2 +18x+81=-4

            -81  -81

x^2 +18x= -85

    /18       /18

x^2= -4.7

\sqrt{x^2}= \sqrt{-4.7}

x= 2.17
