R=16
J=32
20+40(which is 20×2)=60
20-4=16
16×2=32
Solve the equation for x by finding a, b and c of the quadratic then applying the quadratic formula
Go up. This is because the stock price is going up.
We make the composition of both functions:
f (x) = x ^ 2-1
g (x) = 2x-3
Then:
f (g (x)) = (2x-3) ^ 2-1
Rewriting:
f (g (x)) = 4x ^ 2-12x + 8
The domain of this function is all real numbers.
Equivalently
x: (-inf, inf)
answer:
x: (-inf, inf)
option 1.
