Answer:
Option 3
Step-by-step explanation:
we are given the graph of a parabola
with vertex at (0,-1) and symmetrical about y axis and also open up.
Hence the equation of the graph would be transformation of
by a vertical shift of 1 unit down.
So new equation after transformation would be
Or
Hence option 3 is right choice.
Verify:
Put Solving the equation we get
In the graph x intercepts are the same as -1 and 1
Hence our answer is right.
Answer:
(e) (27, 2) and (243, 18)
(g) (63, 9) and (84, 12)
(d) (45, 15) and (60, 20)
(c) (27, 12) and (72, 32)
(a) (15, 30) and (20, 40)
(b) (12, 32) and (18, 48)
(f) (18, 63) and (24, 84)
Step-by-step explanation:
Required
Arrange in increasing order of slope
Slope (m) is calculated using:
So, we have:
(a) (15, 30) and (20, 40)
(b) (12, 32) and (18, 48)
(c) (27, 12) and (72, 32)
(d) (45, 15) and (60, 20)
(e) (27, 2) and (243, 18)
(f) (18, 63) and (24, 84)
(g) (63, 9) and (84, 12)
From least to greatest slope, the pair of points are:
(e) (27, 2) and (243, 18)
(g) (63, 9) and (84, 12)
(d) (45, 15) and (60, 20)
(c) (27, 12) and (72, 32)
(a) (15, 30) and (20, 40)
(b) (12, 32) and (18, 48)
(f) (18, 63) and (24, 84)
