PLZ HELP ME!!!! I NEED THE ANSWER QUICK SO IM GIVING BRAINLIEST TO THE FASTEST AND BEST ANSWER.
geniusboy [140]

Answer:

f(x) = 8(1/2)^x.

Step-by-step explanation:

According to the graph, there is a point at (0, 8) and (1, 4).

That means that when x = 0, y = 8.

8 = a(b)^0

1a = 8

a = 8

That means that a = 8, and when x = 1, y = 4.

4 = 8(b)^1

4 = 8b

8b = 4

b = 4/8

b = 1/2

So, f(x) = 8(1/2)^x.

Hope this helps!

What is the gradient of the blue line?? Mathswatch
yaroslaw [1]

Answer:

gradient = -5

Step-by-step explanation:

A line passes (x1, y1) and (x2, y2) has the gradient (slope) which is calculated by:

gradient = (y2-y1)/(x2-x1)

As shown in picture, this blue line passes (-1, 0) and (0, -5)

=> gradient = (-5 - 0)/(0 - -1) = -5/1 = -5

Hope this helps!
