You are going from a very small number (like - 100000) to a very large number (like + 100000).

But neither of those could be the answer. They are either not small enough or not large enough. The domain must look like this.

- ∞ < x < ∞

Answer: So the domain is all the real numbers.

60 total fourth graders and 43 are girls. To find the number of boys, subtract.

60 - 43 = 17 boys

If 5 girls were absent, subtract.

43 - 5 = 38 girls present

If 4 boys were absent, subtract.

17 - 4 = 13 boys present

Therefore, there were 13 boys present.

Best of Luck!

Here the given expression is

$y =(\frac{3}{4})^x$

We need to find the value of y when x =3 . So we substitute the value of x in the given expression.

$y =(\frac{3}{4})^3 = \frac{27}{64} =0.4$

So when x=3, y=0.4 and that's the required answer.
