Yes that is correct ma dude
The last one represents a function ..
I hope this helps you
-4x-2y+4x+8y= -12-24
6y= -36
y= -6
-4x-2. (-6)= -12
-4x+12= -12
-4x= -24
x=6
(6, -6)
For f(-2), x will equal -2.
Plug the x-value into the equation:
A negative exponent means that the term turns into a fraction, with 1 as the numerator and the positive exponent as the denominator.
Solve 2^(-2):
Solve the problem:
f(-2) will equal
1/2.
