I can't write the symbol, but it would be X<30 and the <would have a horizontal line under it so that it would mean x is less than or equal to 30
2 1/2 .need 20 characters to post
The x-intercept of the line is (-5,0) and the y-intercept is (0,5)
5/7, I don't know what that is as a decimal, but I hope it helps
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
