Question

Express 6+%2B+4x+-+x%5E2 in the form a+-+%28x+%2B+b%29%5E2, where a and b are integers.
ii) Find the coordinates of the turning point of the curve y+=+6+%2B+4x+-+x%5E2 and determine the nature of this turning point.​

Answer 1

Answer:

sorry I didn't know the answer

Answer 2

Answer:

y+=+6+%2B+4x+-+x%5E2

"turning point" is at the vertex, where the x coordinate is at:

x = -b/(2a)

x = -4/(2(-1))

x = -4/(-2)

x = 2

.

find y by plugging it into equation:

y+=+6+%2B+4x+-+x%5E2

y+=+6+%2B+4%282%29+-+2%5E2

y+=+6+%2B+8+-+4

y+=+10
