Remember, for
the x value of the vertex is
so
given
x value of vertex is -5
and
multiply both sides by a
5=-5a
divvide both sides by -5
-1=a
a=-1
comlete the square
remember if we do
(h,k) is the vertex
I know, we can subsitute the known values of te vertex
-5 for h and 20 for k then expand
a=-1
c=-5
Answer:
((1 × 2) + 3) × 4 × 5 + 6 - 7 - 8 + 9 = 100
Step-by-step explanation:
((1 × 2) + 3) × 4 × 5 + 6 - 7 - 8 + 9 = 100
= (2+3) x 4 x 5 + 6 - 7 - 8 + 9
= 5 x 4 x 5 + 6 - 7 - 8 + 9
= 100 + 6 - 7 - 8 + 9
= 115 - 7 - 8
= 115 - 15
= 100
Hi there! :)
C. has both jump and infinite discontinuity.
Evaluate both piecewise functions at x = 1;
1 / (x + 1) = 1 / ((1) + 1) = 1/2
2x - 1 = 2(1) - 1 = 1
As the piecewise functions contain different y-values when evaluated at
x = 1, there is a jump discontinuity at x = 1.
However, the first function also contains a vertical asymptote or infinite discontinuity where it is undefined, or at x = -1. (1 / 0 = undefined). This means that the function also contains an infinite discontinuity.
Therefore, the correct choice is:
C. has both jump and infinite discontinuity.
