Answer:
Domain = ( -∞ , ∞ )
Range = ( ∞ , ∞ )
Step-by-step explanation:
A function is given to us and we need to find the domain and range of the given function .
<u>The </u><u>function</u><u> </u><u>:</u><u>-</u><u> </u>
Definitions :-
- <u>Range </u>:- The range is the set of all valid y values .
- <u>Domain</u> :- All real numbers except where the expression is undefined.
In this case, there is no real number that makes the expression undefined. Therefore the domain will be :-
<u>Domain</u><u> </u><u>:</u><u>-</u><u> </u>
or
<u>Range </u><u>:</u><u>-</u><u> </u>

Answer:
y = 4x - 30
Step-by-step explanation:
The general slope-intercept equation for a straight line is
y = mx + b
For y = 4x – 3, m = 4
=====
The other equation passes through (8,2) and has slope 4:
y = 4x +b Set x = 8, y = 2.
2 = 4×8 + b
2 = 32 + b Subtract 32 from each side
b= -30
The equation for the second graph is
y = 4x – 30
The graph below shows Equation (1) as a red line.
The graph of Equation 2 is the green line that passes through (8,2), runs parallel to Equation (1), and has a y-intercept at (0,-30.
