A quadratic function's graph being wide or narrow is determined or depended on a-term:
If |a| has a lot of value, for example a = 2 or a = 100. The graph will get narrower if increasing the value of |a|. On the other hand, If |a| has small value, for example a = 1/2 or a = 1/10000. The graph would be wide.
Also it does not matter if a-term is negative or not since a-term being positive or negative determines if a parabola is upward or downward. Only |a| determines how narrow/wide the graph is.
From the question, it is clear that the parabola y = 2x^2 is the narrowest graph since it has the highest |a| value out of all choices.
Answer
- y = 2x^2
Answer:
The resistance of the heater is 44 ohms.
Step-by-step explanation:
Given that,
Voltage of electric heater, V = 440 volts
Current drawn by the heater, I = 10 A
We need to find the resistance of the heater. It is a case of Ohm's law. Its mathematical form is given by :
R is resistance of the heater
So, the resistance of the heater is 44 ohms. Hence, this is the required solution.
