Required
Solve for A, C and S
The equations to solve are:
-- (1)
-- (2)
-- (3)
Make C the subject in (3)
Substitute in (1) and (2)
-- (1)
Make S the subject
-- (2)
Substitute
Solve for A
Recall that:
Recall that:
Hence, the result is:
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
