Step-by-step explanation:
Either try all the numbers and see which ones work or do the following.
Times both sides by 2x-5.
3=x(2x-5)=2x^2-5x
Rearrange and solve the quadratic. I will factorise.
2x^2-5x-3=0
(2x+1)(x-3)=0
so x = -1/2 or 3

Answer:
What is the average rate of change from −3 to 0 of the function represented by the graph?
m = (f(0) - f(-3)) / (0 - (-3))
m = (0.5 - 2) / (0 + 3)
m = -1.5 / 3
m = -0.5
