Answer:

Step-by-step explanation:
From the question we are told that:
Function given

Co-ordinates
(x,y)=[1, 4]
Generally the second differentiation of function is mathematically given by

Therefore critical point

Generally the substitutions of co-ordinate into function is mathematically given by
For 1

For 4

For critical point 3

Therefore the maximum value of f(x) = –x2 + 6x over the interval [1, 4] is given by

Answer:
Yes is linear because there is a constant rate of change this is also a function
Slope intercept for is y = -2x+4
Answer:
The least common multiple would be 105.
Step-by-step explanation:
You would do list out the multiples for each. Or multiply
Since 3 x 30 is 90, and 3 x 5 is 15, This is 105
And since 5 x 20 is 100, and 5 x 1 is 5, This is 105 as well
Also, since 7 x 10 is 70, and 7 x 5 is 35, This is 105.
The LCM is 105
Have a great Day!
