domain is {2.4, 4.8, 6.3, 8.8, 10.1 }
For domain, equate f(x) to each value in the range and solve for x
7x - 2.7 = 14.1 ⇒ x = = 2.4
7x - 2.7 = 30.9 ⇒ x = = 4.8
7x - 2.7 = 41.4 ⇒ x = = 6.3
7x - 2.7 = 58.9 ⇒ x = = 8.8
7x - 2.7 = 68 ⇒ x = = 10.1
Answer: It is 2.
Step-by-step explanation:
Make both equation equal to each other and solve for x, as following:
- Add like terms.
- Factor the equation.
Substitute the value of x obtained into any of the original equations to obtain the y-coordinate.
Then, this is:
