Answer:
it is 7x-4
Step-by-step explanation:
Rate of change is like slope. Change in y/ change in x
First we have to solve for the y.
x^2 -3x -4 when x = 7
7^2 -3(7)-4= 24 (7,24)
x^2-3x-4 when x=10
10^2-3(10)-4= 66 (10,66)
(66-24)/(10-7)
42/3 = 14
Answer:
Step-by-step explanation:
MAy yoy make it bigger
Substitute x = -2 in the equation
y = 2/3x + 3
y = (2/3 x 2) + 3
y = 13/3
answer is choice D
