The graph at the right shows a function, f, graphed on the
domain 0 < x < 8.
The section from A to B is a
straight segment.
The section from B to C is
represented by y = (x - 5)^2

1. Find the slope of the segment from A to B.

2. Find the x-coordinate of the relative minimum
value of the graph from B to C.

3. Find the value of f (3) + f (4) + f (6) + f (7).

Step-by-step explanation:

1). Since, line segment AB passes through two points ((0, 0) and (3, 4)

Therefore, slope of the segment =

                                                        =

                                                        =

2). Relative minimum of the graph from B to C → (5, 0)

   Therefore, x-coordinate of the relative minimum → x = 5

3). From the graph attached,

   f(3) = 4

   f(4) = 1

   f(6) = 1

   f(7) = 4

   Therefore, f(3) + f(4) + f(6) + f(7) = 4 + 1 + 1 + 4

                                                          = 10

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
