Carla makes $${21}$$ of her first $${30}$$ free throws of the basketball season and then goes on a streak making every shot after that. Her free throw percentage is modeled by the function $$P(m)={{m+{21}}\over{m+{30}}}$$. As she takes more shots, what does her free throw percentage get closer to?
Use $${f(x)={{x+2}\over{x^2+4x+4}}}$$ to evaluate:
|
a. $${\lim_{x\rightarrow -2}f(x)=}$$ |
b. $${\lim_{x\rightarrow 2}f(x)=}$$ |
|
c. $${f(-2)=}$$ |
d. $${f(2)=}$$ |
|
e. $${\lim_{x\rightarrow \infty}f(x)=}$$ |
f. $${\lim_{x\rightarrow -\infty}f(x)=}$$ |

The following resources include problems and activities aligned to the objective of the lesson that can be used to create your own problem set.
Use $${f(x)={{(x+10)(x-2)}\over{(x+4)(x-3)}}}$$ to evaluate:
|
a. $${\lim_{x\rightarrow -4}f(x)=}$$ |
b. $${\lim_{x\rightarrow 3}f(x)=}$$ |
|
c. $${\lim_{x\rightarrow 2}f(x)=}$$ |
d. $${f(-4)=}$$ |
|
e. $${f(3)=}$$ |
f. $${f(2)=}$$ |
|
g. $${\lim_{x\rightarrow \infty}f(x)=}$$ |
h. $${\lim_{x\rightarrow -\infty}f(x)=}$$ |

Use $${f(x)={{x^2-7x+12}\over{x-6}}}$$ to evaluate:
|
a. $${\lim_{x\rightarrow6}f(x)=}$$ |
b. $${f(6)=}$$ |
|
c. $${\lim_{x\rightarrow\infty}f(x)=}$$ |
d. $${\lim_{x\rightarrow-\infty}f(x)=}$$ |
Use $${g(x)=\left\{\begin{matrix} x+2, & x<-1\\ (x+1)^2+1, & -1\leq x <2 \\ -{1\over x}, & 2<x\leq4 \end{matrix}\right.}$$ to evaluate:
|
a. $${\lim_{x\rightarrow-\infty}g(x)=}$$ |
b. $${\lim_{x\rightarrow\infty}g(x)=}$$ |
Is this function $$g$$ continuous over the interval $${[0, 4]}$$? How do you know?
