(A) Domain of given function is {x | x = –6, –1, 0, 3} as domain means all the value in x sets.
(B) The 2nd graph(3rd figure) is representing the Function as there is an unique value for every x values.But in the other figure there is more than one value for one value of x. (Answer)
Answer:
option 3
Step-by-step explanation:
Answer:
A. 215x + 780 = 2500
Step-by-step explanation:
Multiply both sides of the equation by 100 to eliminate the decimal fractions.
(2.15×100)x + 7.8×100 = 25×100
215x + 780 = 2500
First I would distribute the left part like so:
12x - 18 - (5x + 7)
Then I would distribute the right side like so: (I'm just distributing a negative sign)
12x - 18 - 5x - 7
Then I combine like terms like so: (12x and -5x)
7x - 18 - 7
Then I would combine the other like terms like so: (-18 and -7)
7x - 25
I hope that helps! Feel free to let me know if you have any questions! :3
