Answer:
y=12/x
Step-by-step explanation:
if y=12, and x=1 so
general formula y=12/x
for x=5 , y=12/5=2.4
you can graph by ploting points such as (1,12), (5, 2.4),...
Because the graph is starting high and going down, your answer is c- exponential decay
Answer:
-3/4
Step-by-step explanation:
the rate of change is the slope of the line
7-3/0-(-4) = -3/4
Answer: D
Step-by-step explanation:
No such thing as a vertex of a graph... Eliminate B and C. Try f(3) = 4(3-5)(3+3) is not zero eliminate A. So answer must be D. Check: f(-3) has factor -3+3 = 0. f(5) has factor 5-5 = 0.
Answer:

Step-by-step explanation:
The square of a complex number is a complex number. Here, we have:


We then have this system of equations:


Solving this system:
