Answer. Third option y=4x^2
Solution:
When you multiply a function by a value with absolute value less than 1 you get a wider graph. If you multiply the function by a value with absolute value greater than 1 you get a narrower graph.
In this case we have the quadratic function y=x^2 (parent function)
1. In the first option y=-x^2 we are multiplying the parent function by -1, with absolute value 1, then the width of the graph is the same of the parent function, the minus sign only reflex the graph with respect the x-axis.
2. In the second option y=1/4x^2 we are multiplying the parent function by 1/4, with absolute value 1/4=0.25<1, then we must get a wider graph than the parent function and than the first option.
3. In the third option y=4x^2 we are multiplying the parent function by 4, with absolute value 4>1, then we must get a narrower graph than the parent function and than the first and second option.
4. In the fourth option y=1/9x^2 we are multiplying the parent function by 1/9, with absolute value 1/9=0.11<1/4=0.25<1, then we must get a wider graph than the parent function and than the second option. Of course that this graph is wider than the third oprtion.
Answer: The quadratic function y=4x^2 has the narrowest graph.
Answer:
oxidation takes place at the anode while reduction takes place at the cathode.
Explanation:
In the process of electrolysis the electric current is passed accross an ionic compound, the compound could either be in it's molten state or dissolved in a solvent. When there is connection between the anode and cathode are by a wire, there is always a flow of electrons from anode to cathode.
A redox reaction reffers to a chemical reaction in which there are both process of oxidation and the process of reduction i.e loss of election and gain of electrons occured simultaneously.
During the process of electrolysis, there is oxidation of an ion at anode which is the negative charged electrode, reduction as well takes occur at cathode which is the positively charged electrode at the same time.

Brass is an alloy, and either a "solid solution".
Alloys in general may be solid solutions or they simply be mixtures

Answer:
Should the government invest more money in nuclear energy than
in solar energy
Explanation:
This is because some people might think government should invest in nuclear energy while others might want the government to invest in solar energy.
