What is the range of the function f(x)= 2 + 4 when the domain is {-2, 0, 3}?

Orlov [11]

The domain is the possible input values "x" .. in this case [-4, -2, 0, 2, 4]

The range are the possible output values of f(x)

We need to solve f(x) = 3.2x for each value in our domain

f(-4) = 3.2(-4) = -12.8

f(-2) = 3.2(-2) = -6.4

f(0) = 3.2(0) = 0

f(2) = 3.2(2) = 6.4

f(4) = 3.2(4) = 12.8

What is the the answer to 6/12 x2/3

mr_godi [17]

To multiply two fractions together, multiply the numerators of both fractions together and same goes for the denominators.

$\frac{6}{12} * \frac{2}{3} = \frac{12}{36}$

Simplify.

$\frac{12}{36} = \frac{1}{3}$

So, 1/3 is the answer.
