1. Student id. Every student has a unique student id. So it is a function.
2. The IV curve of resistor. Current voltage of resistor is s direct straight line. Its function as a particular
voltage alwa
1. If a vertical line is moved across the graph it is touching the graph at only one point then the
graph is a function.
At a few x places there is more than one y outputs making it is not a function
Y=0.022*7^2+0.25, y=1.328
First I took the year 2007 and subtracted from the year of 2000. Its come out to be 7. So 7 equals x. I put
the 7 in the equation for x. Square 7 to be 49. 49 times by 0.022
1 a) The fixed monthly cost is $18000
The cost per calculator is $8 with x being the number of calculators
C(x) = 18000+ 8x
b) We get the average cost by dividing by x
C= 18000+8/x
c i) Average cost w
1. An arithmetic sequence is a sequence is in which each term after the first differs
from the preceding term by a constant amount. The difference between consecutive
terms is called the common differ
1. What is an exponential function? It is a constant raised to a power of.
2. What is a natural exponential function? The function A, is the number in the function.
3. Evaluate 4^-1.5 using a calculat
1. A: by looking at the graph the cars value is y=20000-2800x
B: x=5 put in 5 in the substitution of x. y=20000-2800*5 and you should get 6000 because 5
times 2800 is 14000 and 20000 minus from 14000
