To get the vertex of the parabola we proceed as follows;
y=-7(x-4)^2-5
The above can be written as:
y=-7x^2+56x-117
The values of a,b and c are:
a=-7, b=56 and c=-117
x=-b/(2a)
x=-56/(-7*2)=4
but;
y=-7x^2+56x-117
y=-7(4)^2+56(4)-117
y=-5
Thus;
x=4 and y=-5
The vertex will be at point (4,-5)
Answer:
C. y = 2 (x + 3)³ − 4
Step-by-step explanation:
y = x³
Stretch vertically by 2.
y = 2x³
Shift horizontally 3 units to the left.
y = 2 (x + 3)³
Shift vertically 4 units down.
y = 2 (x + 3)³ − 4
Answer:
−7(x + 3) + 8(1 + 8x)=57x - 13
Step-by-step explanation:
Answer:
5/11 is 0.4555555555555555555555555
so basically the first option out of the two.
U do know you can just calculate this with the calculator right?
well if you do it correctly 12/2 is 6 then when you get the 6 and take wawy 4 you will get 2
