Answer:

Step-by-step explanation:
Rate of change is another term for the slope.
rate of change = slope = (change in y)/(change in x)
<u>Function A:</u>
y = mx + b (m = slope)
y = 4x - 3
Function A has a slope of 4.
The rate of change for function A is 4.
<u>Function B:</u>
Take two points.
(-1, 0) and (1, 4)
slope = (y2 - y1)/(x2 - x1)
slope = (4 -0)/(1 - -1)
slope = 4/2 = 2
The rate of change for function B is 2.
Answer:
472.5
Step-by-step explanation:
always put the 1st number you would like to turn to scientific notation
so the 1st number here is 3
then you turn 8 into a decimal because it is the only other number that isnt 0 and then it is 3.8
you then count every number after 3 including 8 which is
then you always put 10 x whatever number you are doing but right now it is 3.8
and the answer is
10 x 3.8^7
You substitute the x with 1
Y=-2x(1)+8
So y = 6
Well as you can see it is F!
