y - 3x = 7
can be written as
y = 3x + 7
For every value of x there is a unique value of y. For example when x = 0 y = 3(0) + 7 = 7
Yes it is a function.
In particular it is a one-to-one function.
Answer:
y = 2
Step-by-step explanation:
3y - 4 = 6 - 2y
+2y +2y
5y - 4 = 6 (new equation)
+4 +4
5y = 10 (new equation)
/5 /5
y = 2
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
