okay, Part A. We know that we can do the question role so one times X minus one minus X plus one times one over the denominator squared. Remember the formulas F one G minus After you won over G squared The simple question negative, too. Over X minus one squared and then we can write a D ax. After this. Maybe wanting to part B. We have negative two over two minus one squared times 0.5 gives us t y equals negative 0.1.
