y = log[8](x)

Vertical compression of 2/3

y = (2/3) * log[8](x)

Shift down 9 units

y = (2/3) * log[8](x) - 9

y intercept when x = 0

so for 1.)

f(0) = 3^0 + 1
f(0) = 2 ? y intercept.

domain is all real numbers, x can be any negative number as well, eg 3^(-1) + 1 = 4/3

so on the graph for coordinate -1 the corresponding y value is 4/3.

etc, and as you input x as x ? -infinity you get the asymptote, which is 3^-99999 + 1,

and if you put x ? infinity you get the other asymptote

Which of the following does not apply to NAD+’s functions?

1. NAD+ is reduced to NADH during both glycolysis and the Krebs cycle.
2. NAD+ can receive electrons for use in oxidative phosphorylation.
3. NAD+ is reduced by the action of dehy- drogenases.
4. NAD+ has more chemical energy than NADH.
5. In the absence of NAD+, glycolysis cannot function.

well when you take the inverse of any function, the domain and range switch. For trigonometric functions, however, the inverse would not be a function because it would not pass the "vertical line test", therefore you have to restrict the domain.

for example:
sin(x)
D: pi/2 to -pi/2
R: 1 to -1
arcsin(x) [another way of saying sin^-1(x)]
D: 1 to -1
R: pi/2 to -pi/2

now say you want to find the arcsin(1/2)
looking at the unit circle, we know that the sine function is = to (1/2) at the angle pi/6 (radians)
so the arcsin(1/2) = pi/6 (radians)

so the arcsin(3/5) = 4/5
