Small triangle : (1,4), (3,1), (3,4)
The x: (3,2)
The big triangle: (-3,3), (-1,5), (-2,1)

(For the big triangle that is only correct if the black dot is the mirror line)

Given the cost function, C(x), and the revenue function, R(x), find the number of units x that must be sold to break even

tresset_1 [31]

P(x) = R(x) - C(x) Breaking even is the point where revenue starts to overtake cost. It is, therefore, the point where P(x) = 0. Since these are all linear functions, you know that after that point the business is profitable. P(x) = 0R(x) - C(x) = 015000x - (9000x+72000) = 015000x - 9000x - 72000 = 06000x - 72000 = 06000x = 72000x = 72000/6000x = 12 At 12 units the business breaks even.

If f(x) = 0.5x and g(x) = 0.25x. Which statement is true?

ra1l [238]

I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
PLEASE SEE ATTACHED IMAGE.

First, we rewrite both functions correctly:
f (x) = 0.5 ^ x
g (x) = 0.25 ^ x
We observe that they are exponential functions, where, rewriting:
f (x) = (1/2) ^ x
g (x) = (1/4) ^ x
We observe that both graphs present an exponential decay where, f (x)> g(x), since, the rate of change of f (x) (1/2) is greater than the rate of change of g (x) ( 1/4).
Answer:
as -> infinity, f (x)> g (x) *
