The plot below represents the function f(x)

How do I evaluate and solve these expressions??

9514 1404 393

Step-by-step explanation:

a) Find 3 on the x-axis. Locate the point on the graph where the vertical line x=3 intersects it. Find the y-coordinate of that point.

The point of intersection is (3, 4). Then f(3) = 4.

b) Find 3 on the y-axis. Locate the point on the graph where the horizontal line y=3 intersects it. Find the x-coordinate of that point.

The point of intersection is (-3, 3). Then f(-3) = 3; x = -3.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
