Solving equation s(r(x)) for x= -3, you find as result s(r(-3))=-64
Solving Equations
The equations can be solved when you replace the variable x for a given value or find the zero of functions.
The question gives:
r(x)=2x-2
s(x)=-x²
First, you will find r(-3). For this, in the equation r(x)=2x-2, you should replace x for -3. Then,
r(x)=2*(-3)-2
r(x)=-6-2= -8
Like r(-3)= -8, you should replace x, in s(x), for -8.
s(x)=-(-8)²
s(x)=-64
Hence, s(r(-3)=-64.
