PLS HELP!!! Which of the following is true for the relation f(x) = x2 + 8? Only the inverse is a function. Neither the equation nor its inverse is a function. Both the equation and its inverse are functions. Only the equation is a function.

5 months agois the 2 supposed to be an exponent? anyways, just sketch the graph and see if it passes the horizontal and vertical line tests

5 months agoyes the 2 is an exponent what are the horizontal and vertical line tests?

5 months agograph the function 1. vertical line test: if you can draw a vertical line anywhere so that it crosses the function more than once, the original relation is not a function 2. horizontal line test: if you can draw a horizontal line anywhere so that it crosses the function more than once, the inverse is not a function

5 months agowell it's x^2 + 8 not just x^2 but it doesn't really matter in this case so taking a look at your function, can you draw any sort of vertical line that would cross the function more than once?

5 months ago@kittybasil thanks

5 months ago@Vocaloid I don't think so, not a straight line

5 months ago❓❔

5 months agogood so the original relation is a function what about a horizontal line?

5 months agowe can draw a horizontal line though, right?

5 months agoyes so the inverse is not a function therefore "Only the equation is a function." ---> your sol'n

5 months agoHere's your function, sorry about that
