If f(x) = 2x – 1 and g(x) = x2 – 3x - 2, find (f + g)(x).
o
a. (f+ g)(x) = -x-3

b. (f + g)(x) = x2 - x - 3

c. (+ g)(x) = x + 5x + 3

d. (f+ g)(x) = x-3

Option B

Step-by-step explanation:

In this problem we have the function

and the function

They ask us to perform the operation:

Therefore we must perform the algebaic summa of the function f plus the function g

Now we siplify the expression

-6 is the correct option from the above given options

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.
