Given:
f(x) = 4x -3
g(x) = x- 5
Determine (fºg)(14)
Solution:
The condition can be read as f of g,meaning we will insert the value of g(x) at f(x).
(fºg)(14) = 4(x - 5) -3
(fºg)(14) = 4x - 20 -3
Substitute x with the value of 14.
(fºg)(14) = 4(14) - 20 -3
(fºg)(14) = 4(14) - 23
(fºg)(14) = 56 - 23
(fºg)(14) = 33
Final answer:
(fºg)(14) = 33
