The given functions are

Evaluate the functions.
1. Because 7/4 > 1 and the exponent is positive,
the function does not decay.
2.Because 4/5 < 1 and the exponent is negative,
the function does not decay.
3. Because 8/7 > 1 and the exponent is negative,
the function decays.
4. Because 9/2 > 1 and the exponent is positive,
the function does not decay.
A composite plot the functions verifies the answer.
Answer:
The answer is z ≥ -6/5 :)
Answer:
A pie graph would be a good graph to use
Answer: infinitely many and none
Step-by-step explanation:
if all variables cancel and you are left with zero, there are infinitely many solutions. if it is false there are no solutions.
