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.
Perimeter of the square backyard=56m
Perimeter of a square=4*side
Side=
56=4*side
56/4=side
side=14 cm
Area of a square=side*side
=14*14
=196cm^2
So,the area of the square backyard is 196m^2.
