So if we want to determine whether this is a 1 to 1 function, what we want to do is start by plugging into our cherry values, um, setting the function equal to each other and then seeing if a has to be eager to be or to arbitrary bodies have to be the same value. So let's go ahead and start. So we have our of A is able to r B. So on the left side, lead up to minus five times a all square bruited is equal to two minus five b all square root. So now we could first start by the square. Any chides the square and square roots go away. That would give us to minus five. A is equal to minus five B. We could go ahead and subtract two on each side, so the twos canceled that we have minus five. A is in Britain minus bi bi. Then we could go ahead and divide each side by negative five, which would give us A is able to be. And so this now implies R of X is one toe. One end. Since we've proved just one toe one, you could go ahead and put a bullet proof box and a smiley face
