a = 8, b =

Step-by-step explanation:

Given the exponential function

f(x) = a

To find a and b use the given coordinate points on the graph

Using (0, 8 ), then

8 = a [ = 1 ] , then

a = 8

f(x) = 8

Using (2, 18 ) , then

18 = 8b² ( divide both sides by 8 )

= b² , that is

b² = ( take the square root of both sides )

b = =

Thus

f(x) = 8

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
