3. If the line tangent to the graph of the function f at the point (1,7) also passes through the point
Usimov [2.4K]

Answer:

f'(-1)= 3

Step-by-step explanation:

slope = (y2 - y1)/(x2 - x1)= (7-(-2))/(1-(-2))=9/3=3

Slope of the tangent line in the given point equals f' at this point.

So,

I only need the step by step process I know the answer. emergency someone please answer! Will mark best answer
Leokris [45]

Step-by-step explanation:

1. y=(x-2)²-9

Using Formula (a-b)²=a²-2ab=b²

y=(x²-4x+4)-9

y=x²-4x-5

Using Mid term Break

y=x²-5x+x-5

y=x(x-5)+1 (x-5)

y=(x+1)(x-5)

2. y= -(x-5)²+16

Using the same formula as above

y= -(x²-10x+25)+16

y= -x²+10x-25+16

y= -x²+10x -9

Taking (-) as Common

y= -(x²-10x+9)

y= -(x²-9x-x+9)

y= -[x(x-9)-1(x-9)]

y= -(x-1)(x-9)
