Solving for limits of linear functions approaching infinity. Example problem: Find the limit of 2x + 2 as x tends to 0. Step 1: Repeat the steps as above, but this time solve for the limit as x approaches infinity. f(x) = 2x + 2 c = ∞ lim(x→&infin) 2x + 2 = lim(x→&...
It means that you’re plugging in larger and larger x-values (i.e. x-values that are getting closer and closer to infinity) to see what happens. Limits answer the question “Which number did this function get to?” as well as “Which number did this function try to get to?”. In ...

Tip: If you want to enter ∞ (infinity) as one of your lower or upper values, press the diamond key and then Catalog.Normal Distribution Problems using ExcelWhile it’s possible to look up probabilities for a normal distribution using the z-table, it’s much easier to calculate probabilitie...
R4 represents four dimensions and so on. It’s practically impossible to deal with Rn vector spaces, because they contain every possible vector of n dimensions, up to infinity. Instead, we use subspaces, which are smaller vector spaces within a Rn vector space. Back...
make a visual judgement. In the image below, the polynomial has a relative maxima at 2 and relative minima at 4 and -2. The relative minima at -2 is also a global minima; the absolute maxima doesn’t exist because the value of the polynomial goes toward positive infinity at both ends....
If you insert a few x-values between 2 and 3 into (x2 –9), you’ll see that the function approaches negative infinity. Insert some more x-values greater than x = 3, note that the function tends toward positive infinity. The larger the x-values get, the smaller the function values ...
