A ) The domain:
x ≤ -4 and x≥ 4 or: x ∈ ( - ∞ , - 4 ) ∪ ( 4 , + ∞ )
b ) f ` ( x ) =
c ) The slope of the line normal to the graph at x = 5
m = -1 / f `(x)
f ` ( x ) =
m = - 3/34
For
the discriminant is
there are 3 basic cases of what happens for different discriminants
1. if the discriminant is less than 0, then there are no real zeroes
2. if the discriminant is 0, then it has 1 zero
3. if the discriminant is greater than 0, it has 2 zeroes
so given
a=3,b=-7,c=4
thus the discriminant is
the discriminant is 1. 1 is positive, thus the equation has 2 zeroes because the discriminant is greater than 0
the answer is the equation has two zeroes because the discriminant is greater than 0
M= a number
> = more than/greater than
Expression:
m - 3 > -4
If you have to also solve:
m - 3 > -4
add 3 to both sides
m > -1
ANSWER: expression is m - 3 > -4;
expression solved for m is m > -1
Hope this helps! :)
The two that use scientific notion incorrectly are...
G: two places before the decimal when there should only be one.
H: there is no decimal.
