Answer:
(f - g)(x) = + 8x + 4
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= + 10x - (2x - 4) ← distribute parenthesis by - 1
= + 10x - 2x + 4 ← collect like terms
= + 8x + 4
Answer:
x=2, or x=1
Step-by-step explanation:
Given the equations as
f(x)=2x and
g(x)=2^x
Using a graph tool the equations will intersect at points (2,4) and (1,2)
x =2 or x=1
