it's clear. So a new ranger So we're given why is equal to one over one plus x square. So we need to find the derivative of this and we're gonna use the quotient role, which gives us one plus x square. Comes the derivative of one minus one times the derivative of one plus X square all over one plus x square square. And this gives us negative to X over one plus x square square. No, we plug in to find a slope and we get 1/2 when we substitute the equation for why minus 12. 1/2 is equal to em. Times X plus one we get Why minus one have this equal to 1/2 times X plus one. And this becomes why is equal to when have X plus one. And for part B, we're gonna draw our graph. You don't look like this in our tangent line in red
