Real numbers are all the rational numbers such as -7 and 4/3 and all irrational numbers. Real numbers are used mainly in counting and are used in measurement which is always present in real-world situations. These numbers help us to quantify things around.

Answer with explanation:
To solve , f(x)=g(x)
The three methods that we generally use to solve above equation is
1.→ Graphing technology
2.→Tables of values
3.→Successive approximation
→If you will use "Table of values" ,you will substitute the value of x in both f(x) and g(x) ,so after hit and trial you can find exact value of x, where , f(x)=g(x).
→The method of "Successive approximation" is used by selecting an Interval and then values of x are substituted from the interval to calculate the exact value of x for which, f(x)=g(x) by hit and trial method.Little bit lengthier and time consuming.
→ "Graphing technology"=Draw graph of both f(x) and g(x) .The point where these two function intersect gives the value of x.Tough to draw the graph of some function but gives exact answer once you have accomplished the drawing of Graph.
⇒"Graphing technology" is the method that would be preferred to calculate ,f(x)=g(x), to calculate x.
Easy
ok, so
for y=a(x-h)^2+k
the vertex is (h,k)
given that the the vertex is (-2,-20)
y=a(x-(-2))^2+(-20)
y=a(x+2)^2-20
find a
when x=0, then y=-12
-12=a(0+2)^2-20
-12=a(2)^2-20
8=4a
2=a
equation is
y=2(x+2)^2-20
if the last term is positive, then maybe y=2(x+2)^2+(-20)?
unless you typed something wrong, then you are right that the last term is -20
