A) For the following function, use the given set of intervals to estimate the slope of the tangent line of the function at x=−2 x 2 by producing the slopes of the secant lines that pass through the x x-values of each of the intervals. f(x)=2x2+1;[−4,−2],[−3,−2],[−2.5,−2 ],[−2.25−2] b) For the following function, use the given set of intervals to estimate the slope of the tangent line of the function at x=6x6by producing the slopes of the secant lines that pass through the xx-values of each of the intervals.
f(x)=3x2;[6,8],[6,7],[6,6.5],[6,6.2 5]

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.
