Answer:
Step-by-step explanation:
A quadratic function has the formula ax² + bx + c
- To determine if a graph will be narrow or wide, the leading coefficient, a, will be the factor that determines this
- The greater the coefficient, the narrower the parabola
- The lesser the coefficient, the wider the parabola
Here all of the functions are in the form ax²
- In
, our "a" term is 
- In y = -2x², our "a" term is -2
- In y = -3x², our "a" term is -3
- In
, our "a" term is 
We can eliminate the two functions with the negative coefficients because they are much smaller than the two functions with the fractions as coefficients, and will therefore open much wider.
We can now compare the two remaining functions, and 
- Giving the two fractions common denominators would turn them into
and 
- The equation with the larger fraction will be the parabola that is the narrowest. In this case, it is the .
- Therefore, will have the narrowest graph

Answer: 5%
Step-by-step explanation:
if it was 2.90 yesterday and 2.85 today there is a 5 cent decrease. to find the percent you convert .05 to a percent which is 5%
First, I solve the equation: 5^7+5^6...
I got 93750
--
The divisibility rules of 6 are:
- It must be divisible by 2
- It must be divisible by 3
So, let's check if 93750 is divisible by 2 first.
It's in even number which automatically means that it is divisible by 2.
No odd numbers are divisible by 2
--
Now let's check if it is divisible by 3 second.
The divisibility rules of 3 are:
- The digits added must be divisible by 3
So, 9 + 3 + 7 + 5 + 0 = 17
17 is NOT divisible by 3.
--
Therefore, your equation is not divisible by 6!
