Mathematics
1 answer:
Marrrta [24]3 years ago
3 0

Answer: A quantity grows exponentially when its increase is proportional to what is already there. A common example is compound interest, where $100 invested at 7% per year annual compound interest will double in 10 years. Similarly, if a population grows at 7% per year, it, too, will double in 10 years.

Stocks have a higher rate of return than either U.S. treasury bills or bonds.  
 C) Small company stocks and large company stocks  
Note: Small company stocks generally have a higher rate of return than large company stocks. Small company stocks are a riskier investment because they are more volatile. Stock investments in general are riskier investments than treasury bills or bonds. In general, the possible rate of return increases as the risk of the investment increases.

19. If f(x) = 6x + 3, find f-1(x).
KengaRu [80]

Answer:

f^{-1}(x) = \frac{x-3}{6}

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 6x + 3 ( subtract 3 from both sides )

y - 3 = 6x ( divide both sides by 6 )

\frac{y-3}{6} = x

change y back into terms of x, thus

f^{-1}(x) = \frac{x-3}{6}
