Answer:
(-4, 8)
Step-by-step explanation:
Answer:

Step-by-step explanation:
We are given:

And we want to solve for <em>x</em>.
First, we can add 49 to both sides:

Now, we can take the square root of both sides. Since we are taking an even root, we will need plus-minus. Hence:

Evaluate:

Subtract 7 from both sides:

So, we have two solutions:

Evaluate:

So, from least to greatest, our solutions are:

Answer:
Set the denominator in 4x equal to 0 to find where the expression is undefined. x=0
The domain is all values of x that make the expression defined.
Interval Notation: (−∞,0)∪(0,∞)
Set-Builder Notation: {x|x≠0}
The range is the set of all valid y values. Use the graph to find the range.
Interval Notation: (−∞,4)∪(4,∞)
Set-Builder Notation: {y|y≠4}
Determine the domain and range.
Domain: (−∞,0)∪(0,∞), {x|x≠0}
Range: (−∞,4)∪(4,∞), {y|y≠4}
Step-by-step explanation:
3 quarters, and two thirds of a quarter so It's [3 2/3]
