Answer:

3^-3 for the first answer. The second answer is 3^7.

Step-by-step explanation:

If you multiply two numbers with the same base and exponents, the exponents are added up.

If you divide two numbers with the same base and exponents, the numerator would subtract the denominator.

So the answer to the first question is 3^-3. The second answer would be 3^7.

Find the range of f(x) = –x + 4 for the domain {–3, –2, –1, 1}.

marishachu [46]

Answer:

$\boxed{ \{7, 6, 5, 3 \} }$

Step-by-step explanation:

The domain is all possible values for x.

The range is all possible values for f(x) or y.

The domain given is {-3, -2, -1, 1}.

Plug x as {-3, -2, -1, 1} and find the f(x) or y values.

$f(-3)=-(-3)+4=7\\f(-2)=-(-2)+4=6\\f(-1)=-(-1)+4=5\\f(1)=-(1)+4=3$

The range is {7, 6, 5, 3}, when the domain is {-3, -2, -1, 1}.
