Answer:
RoC is 0.75 (3/4); Equation is y=0.75x
)
Step-by-step explanation:
You can easily spot that first column, x increases by 1 each line, while the second, y, increases by 0.75.
Rate of change is variation in y divided by the variation in x, or
. Replacing with the value we found, we get that the rate of change is
or
.
To find the equation the easiest way is to go back 4 steps, at the same rate of change, in order to find what's the value for x=0. Going back by 0.75 each step starting from 4, we obtain 2.25, 1.5, 0.75, and finally 0. Our equation becomes
104.818891427

Answer:
As x increases , y decreases then increases
Step-by-step explanation:
There are two situation
1> when x < 0
2> when x>= 0
let see
when x < 0
we see that as value of x moves from -ve value towards zero (i.e x is increasing) then value of y is decreasing( value of x has moved from positive side of y( above x-axis) towards negative side of (below x-axis)\
Thus, we can say that
for x < 0
As x increases , y decreases
________________________________________
when x>= 0
we see that as value of x moves from 0 towards +ve value(i.e x is increasing) then value of y is increasing( value of x has moved from negative side of y( below x-axis) towards positive side of (above x-axis)\
Thus, we can say that
for x >= 0
As x increases , y increases
_________________________________________
combining both observation it can be said that
As x increases , y decreases then increases which is equal to fouth option
