Plz ! 17 points! 2. what is the domain of the function {( 1, 1), {0, 0}, ( 2, -1)} ? a. {-1, 0, 1} b. {-1, 0, 1, 2} c. { 0, 1, 2} d. {(1, 1), {0, 0}, (1, 0), (2, -1)} 3. suppose that the function f(x) = 5x + 3 represents the number of cars that drive by in x minutes. how many cars will drive by in 10 minutes? a. 80 b. 53 c. 50 d. 35

2.  C. { 0, 1, 2}

3.  B. 53

6.  P = 14n + 10

Step-by-step explanation:

2.  The domain is the input values (or the x values)

The domain is { 0,1,2}

3.  f(x) = 5x+3

 where x is the number of minutes.  We will let x = 10

f(10 ) = 5*10 +3

       = 50+3

      = 53

53 cars will pass

6.  When we have 1 trapezoid, the perimeter is 5+5+8+6 = 24

When we have 2 trapezoids, the perimeter is 5+8+6+5+8+6 = 38

We add 14, when we add a second trapezoid

P = 14n + 10

p(1) = 14+10   Check for 1 trapezoid

p(2) = 14*2 +10 = 28+10 = 38    check for 2 trapezoids

2. You're given a function that maps 1 to 1, 0 to 0, and 2 to -1. The domain is the set of points that are given to the function as inputs, {1, 0, 2}, which is equivalent to the set listed in option C.

3. Evaluate at :

so the answer is B.

6. Each trapezoid in the chain contributes a copy of 8 and 6 (a total of 14), so that we should expect the total perimeter to contain . The remaining two sides contribute a constant 10 regardless of . So the perimeter is given by the formula in D, .

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
