Anyone help me ASAP, its due in an hour, plz show all the working, THANK YOU SO MUCH

Leona [35]

Answer:

Step-by-step explanation:

First, start out with the parent function:

$y = b^{x}$

Now, we look at the transformations, and make the equation.

We see that the graph <u>shifted down 4 units</u>, since the <u>graph's horizontal asymptote</u> is at y = -4.

$y = b^{x} - 4$

We see point (0, -3) to point (1, -1). The value of b would be 3. The reason is that when you <u>plug 0 in, you get 1, then 1 - 4 equals 3. (0, -3),</u>

<u>Then, when you plug in 1, you get 3, then 3 - 4 equals -1. This matches up with the graph.</u>

This is the answer:

$y = 3^{x}-4$

Which equation describes the circle

deff fn [24]

Answer:

B. (x-5)²+(y+1)² = 49

Step-by-step explanation:

An equation of a circle with center (h, k) and radius r is

$\large \boxed{ {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} }$

We have all given information we need. Our h is 5 - Our k is -1 and our radius is 7

Substitute these values in

$\large{ {(x - 5)}^{2} + {(y - ( - 1))}^{2} = {7}^{2} } \\ \large{ {(x - 5)}^{2} + {(y + 1)}^{2} = {7}^{2} } \\ \large{ {(x - 5)}^{2} + {(y + 1)}^{2} = 49 }$

So the answer is B choice.
