Answer:

We now want to find the best approximation to a given function. This fundamental problem in Approximation Theory can be stated in very general terms. Let V be a Normed Linear Space and W a finite-dimensional subspace of V , then for a given v ∈ V , find w∗∈ W such that kv −w∗k ≤ kv −wk, for all w ∈ W.

Step-by-step explanation:

Select the correct answer.
lianna [129]

Answer:

B

Step-by-step explanation:

Given g(x) then g(x + a) is a horizontal translation of g(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then a shift to the right of a units

h(x) = g(x - 3) = (x - 3)² with a < 0

The graph of h(x) is the graph of g(x) horizontally shifted right 3 units

there are 20 guests at a party the host has 8 gallons of punch he estimates that each guess within 2 cups of punch if his estima
AlekseyPX
STEP 1:
convert gallons to cups & calculate total number of cups

1 gallon= 16 cups

= 8 gallons * 16 cups/gallon
= 128 cups total


STEP 2:
calculate total cups estimated for 20 guests

= 20 guests * 2 cups/guest
= 40 cups needed for guests


STEP 3:
subtract the difference between step 1 and step 2 to find leftover punch

= 128 cups - 40 cups
= 88 cups leftover

OR

GALLONS LEFTOVER
= 88 ÷ 16 cups/gallon= 5 1/2 gallons


ANSWER: There will be 88 cups or 5 1/2 gallons of punch leftover.

Hope this helps! :)

I actually don’t get this and I have a test in 2 days please help what is g(x) and how
nataly862011 [7]

first off, is noteworthy that's the graph of an exponential function, thus the function will be along the lines of g(x) = abˣ , now, what's "a" and "b" values?

well, let's take a peek when x = 0 and x = 1.

\bf g(x) = ab^x \\\\[-0.35em] ~\dotfill\\\\ \begin{cases} x = 0\\ y = 1 \end{cases}\implies 1=ab^0\implies 1=a(1)\implies \boxed{1=a} \\\\[-0.35em] ~\dotfill\\\\ \begin{cases} x = 1\\ y = 4 \end{cases}\implies 4 = ab^1\implies 4=1b^1\implies \boxed{4=b} \\\\[-0.35em] ~\dotfill\\\\ ~\hfill g(x) = 4^x\qquad \qquad \qquad \begin{array}{|c|c|ll} \cline{1-2} x&y\\ \cline{1-2} -2&\frac{1}{4^2}\to \frac{1}{16}\\ -1&\frac{1}{4}\\ 0&1\\ 1&4\\ 2&16\\ \cline{1-2} \end{array}~\hfill
