Answer:
Step-by-step explanation:
Given that 
and 
are the functions.
To find 
with the given two functions. ie., to find the composite function of f(x) and g(x) which is denoted by
Therefore
Therefore the composite function of f(x) and g(x) is
Answer: x=16
Step-by-step explanation:
Answer:
reflection across the x-axis
Step-by-step explanation:
42 degrees. Since the Ray is the angle bisector, that means it divides angle DEF into two angles with equal measure. So, divide 84 by 2 to get 42.
Step-by-step explanation:
f (10) = 3×10 - 8
= 30 - 8
= 22
f (3) = 3×3 - 8
= 9 - 8
= 1
f(10) - f (3) = 22 - 1
= 21
