Use the power rule
d(x^n)/dx = n·x^(n-1)
to form the derivative.
f'(x) = 4·2x -4
f'(x) = 8x - 4
Now, substitute "a" for "x" to find f'(a):
f'(a) = 8a - 4
Answer:
2/3
Step-by-step explanation:
M= (y2-y1)/(x2-x1)
Plug in the points. (2,3) (9,7)
m= (7-3)/(9-2)
m= 4/7
Slope= 4/7
I hope this helps!

Answer:
Sasha can look at the graph and check to see that when she plots the points on the graph, they end up as a straight line. She can also draw a table to test the values and see if when you divide y/x you get the same answer for all of them.
