Answer:
0.5
Step-by-step explanation:
We find the multiplicative rate of change simply by taking one of the y values and dividing it by the y value right above it.
Here, let's just arbitrarily choose y = 0.125. We divide this by the y value above it, which is y = 0.25:
0.125 / 0.25 = 0.5
So, the multiplicative rate of change is 0.5.

Thought you'd want to know: If you're talking about parabolas, it's parabolas, not probables. ;)
The standard equation of a a quadratic is y = ax^2 + bx + c. We need to find the values of the coefficients a, b and c.
Taking the first point: When x=3, y=0, so write 0 = a(3)^2 + b(3) + c, or
0 = 9a + 3b + 1c
Do the same for points (-2,3) and (-1,4).
You will have obtained three linear equations in a, b and c:
3= a(-2)^2 + b(-2) + c, or 3 = 4a - 2b + 1c, also
4 = a(-1)^2 + b(-1) + 1c, or 1a - 1b + 1c.
I used matrix operations to solve this system. The results are:
a= -2/5, b= 1/5, c= 21/5
and so the function f(x) is f(x) = (-2/5)x^2 + (1/5)x + 21/5.
Answer:
x > 
Step-by-step explanation:
Change the less than sign to an equals sign so we can solve for x
(4-3x)-6 = -4
Reorder the numbers in the parentheses
(-3x+4)-6 = -4
Get rid of the parentheses and combine like terms
-3x-2 = -4
Add 2 to both sides
-3x = -2
Divide both sides by -3
x =
Bkuz you want it to be less than, change the equals sign to a greater than symbol bkuz of the negatives
