Y=x^2+4x-5 what is the axis of symetry

Answers

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

9 x 6 = 54 is this right I'll do distributive property next time

see ok like you cant get 54 with eight so like 8 x 6=48 k so use one of a distributive property you know of k so do 8 x 54 is what find you answer and right it down example: hint its a answer to ur question :identity property 432 x 1 is 432 identity property is one of your distributive property simple done boom.!!!!!!!!!!!!!!!!!

Graph the function. f(x)=5*(4/5)^x

Answers

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.
