Need ! the graph below compares plant height to the age of the plant, in weeks. y=1.3x-0.8 based on the graph, which is the best prediction of the height of the plant at 5 weeks?

a.)4 inches

b.) 5 inches

c.)6 inches

d.)7 inches
will award with brainllest

C) 6 inches

Step-by-step explanation:

Given function:

The function compares plant height in inches to the age of plant in weeks.

So, we can say

represents height of plant in inches.

represents age of the plant in weeks.

In order to predict the height of the plant in 5 weeks, we will plugin in the given function and evaluate

⇒

⇒

⇒ inches

Thus the approximate height of plant in 5 weeks would be inches

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

answer: y=0 if that is what u r looking for
