The domain of the function is given. Find the range.

2 answers:

8 0

The range is how much it spans in f(x), f(x) is a line, it has no max/min, so it's enough to substitute the least and greatest values of your domain:

f(-2) = -5, f(4)=7,

Range = [-5,7]

The range is found by plugging in the values of the domain into 2x - 1
So for x = -2, f(x) = 2(-2) - 1 = -5

The range will consist of -5 and the other 3 values of f(x) found for x = 0, x=2 and x=4.

Answer:

$x = 0$

Step-by-step explanation:

Write the number in exponential form with the base of 2:

${2}^{x - 3} = {2}^{ - 3}$

Since the bases are the same, set the exponents equals.

$x - 3 = - 3$

Cancel equal terms on both sides of the equation:

$x = 0$

1. Identify and EXPLAIN the ERROR

Anit [1.1K]

This might be a trick question. I did the problem and got the exact same answer. I got 31 x + 0.5. If there's anything they did wrong maybe its because they didn't put a zero before 5 so 5 could become a decimal?
