Answer 6

first find the value of function for 1 and 3 .then use this formula
average rate of change=(y2-y1)/(x2-x1)

Answer 7

so that's it?

Answer 9

yep, thats it

Answer 10

thanks guys

Answer 11

if not:
y = mx + c
m is the gradient... which is the rate of change

Answer 12

in this case: y = 2x + 1
so c = 1 and m = 2...

Answer 13

alright thanks

Answer 14

np

Answer 15

The average rate of change is given by:
\[a.r.c. = \frac{f(x_1)-f(x_0)}{x_1-x_0}\]

Answer 16

just plug in the values
