Answer:
a = 3
b = -12
Step-by-step explanation:
gradient function (y') = ax² + b
curve function (y) = 1/3 ax³ + bx + c
pass (1,-11) : -11 = 1/3 a + b + c ..... (1)
pass (2,-16) : -16 = 8/3 a + 2b + c ..... (2)
slope at (2,-16) is 0 (its tangent parallel to x axis)
at (2 , -16) ax² + b = 0 4a + b = 0 b = -4a .... (3)
(2) - (1) : -5 = 7/3 a + b = 7/3 a -4a = -5/3 a ... (4)
3 x (4) : -15 = -5a a = 3
b = -4a = -4 x 3 = -12

Answer:
7.25
Step-by-step explanation:
10,9.75,9.5,9.25,
the rest of the sequence would look like
8, 7.75, 7.5, 7.25, 7, 6.75, 6.5, 6.25, 6 etc.
(the pattern is - .25 from the previous number.
so the 8th number in this sequence is 7.25
hope this helps!!:)
Answer:
-1, 5
Step-by-step explanation:
With the graph, when you switch the x axis, you have to make the additive inverse for the y. If Y, additive the X.
