Just did this. Look below.
Huh?
Look below what?
The question below this one. I answered this enough already. 21/3 = 7
Please just explain it under this question. It would be very helpful :)
if x = 5, y = 5^2 + 3 = 25+ 3 = 28
if x = 2, y = 2^2 + 3 = 4 + 3 = 7
change in y = 28-7 = 21
change in x = 5 - 2 = 3
rate of change = dy/dx = 21/3 = 7
if x = 2, y = 2^2 + 3 = 4 + 3 = 7
change in y = 28-7 = 21
change in x = 5 - 2 = 3
rate of change = dy/dx = 21/3 = 7
oh my god thank you
does that go for average rate of change though?
Pwease answr
yes
