We must plugin values:
3(7)-4(0)=21, is CORRECT since 7•3 is 21 and -4•0 is 0
3(11)-4(3)=21 is CORRECT since 3•11=33 and -4•3=-12 so 33-12=21
3(-3)-4(3)=21 is INCORRECT since 3•-3 is -9 and -4•3 is -12, -9-12 is -21
3(-1)-4(-6)=21 is CORRECT since 3•-1 is -3 and -4•-6 is 24 and so 24-3=21
F(x)= -x^2 -3 (hope this helps)

Answer:
x = 3
Step-by-step explanation:
exponential equation:
nb=a
logarithmic equation: logna=b
If you put in 8 for f(x) your exponential equation is
2x=8
Use the pattern above to change it to a log equation
8 = 2^x
log 8 = log 2^x = xlog 2
log 2^3 = 3log 2 = xlog 2
x = 3
Answer:
8
