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.

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
