Answer:
axis of symmetry: x= -2
Step-by-step explanation:
axis of symmetry = - (b/2a) ( a is the coefficent of x^2, b is that of x)
so a=1, b=4
- (b/2a) = - (4/2) = -2
1 is 5% of 20
because when you multiply 20 by 5 = 100
I hope that's help !

The function `f(x)=5*(4/5)^x` is an exponential function with a base of 4/5. Exponential functions with a base less than 1 decay, so the graph of this function will approach zero as x increases.
To graph the function, we can start by plotting a few key points. The following table shows some key points for the function `f(x)=5*(4/5)^x`:
| x | f(x) |
|---|---|
| 0 | 5 |
| 1 | 4 |
| 2 | 3.2 |
| 3 | 2.56 |
| 4 | 2.048 |
We can then plot these points on a graph and connect them with a smooth curve.
The graph shows that the function decays exponentially as x increases. The function also approaches zero as x increases.
