### Factoring is used to solve quadratics of the form $$\displaystyle{a}{x}^{{2}}+{b}{x}+{c}={0}$$ when th eroots are rational. Find the roots of the following quadratic functions by factoring: a) $$\displaystyle{f{{\left({x}\right)}}}={x}^{{2}}-{5}{x}-{14}$$ b) $$\displaystyle{f{{\left({x}\right)}}}={x}^{{2}}-{64}$$ c) $$\displaystyle{f{{\left({x}\right)}}}{6}{x}^{{2}}+{7}{x}-{3}$$

It is known f that has a removable discontinuity at x =- 1 and $$\displaystyle\lim_{{{x}\to{1}}}{f{{\left({x}\right)}}}={2}$$. Evaluate a) f(0) b) $$\displaystyle\lim{x}_{{{x}\to\infty}}{f{{\left({x}\right)}}}$$

### You have been asked to bake the birthday cake of a little girl who is about to turn three. When looking up suggestions online on how to bake this cake, you found that most everyone suggests baking the cake in smaller circular cake pans that have a diameter of 6 inches. That’s the best way to get the height for the unicorn head. A normal circular cake pan (and the only kind you have) has a diameter of 9 inches. You need to buy cake pans. As an experienced baker, you know that the recipe you are planning on using usually fills two regular (9-inch) cake pans, with a little room to spare. How many 6-inch pans do you need to buy? (We’re going to assume that all cake pans are the same height.)
