Solution:
<u>Note that:</u>
<u>Using cross multiplication:</u>
- (3x)/20 = (4x + 2)/28
- => (3x) × 28 = (4x + 2) × 20
<u>Simplifying both sides:</u>
<u>Subtracting 80x both sides:</u>
- 84x = 80x + 40
- => 84x - 80x = 80x + 40 - 80x
<u>Simplify the LHS:</u>
- => 84x - 80x = 40
- => 4x = 40
- => x = 10

Answer:
The answer to your question is below
Step-by-step explanation:
Domain of a function is the complete set of possible values of "x".
In a radical function, domain must be ≥ 0.
Exercise
f(x) = 
Then
x + 4 ≥ 0
x ≥ -4
Domain is x ≥ -4 or [-4 , ∞)
