What value of k will make this relationship NOT a function?
devlian [24]

Answer:

the correct answer is b.

Step-by-step explanation:

it is b because if you plug in -7, two of the x-values will have -7 making the x-values the same and in order to be a function all x-values have to be different.

Elanso [62]

Answer:

Sophie

Step-by-step explanation:

For each runner, divide their time running by the laps they ran.

Piper: 8÷3≈2.7

Walker: 25÷10=2.5

Sophie: 3÷1=3

Sophie takes the longest time to run one lap, she is the slowest.

State a cubic or quartic function with the least degree possible in intercept form for the given graph. Assume that all x-interc
Iteru [2.4K]

Answer:

y = -x^{3} - 2x^{2} + 5x + 6

Step-by-step explanation:

The function will be cubic.  The x-intercepts are -4, -1, and 2

The constant factor is -1 because the graph falls on the right.  So,

y = -(x + 4)(x + 1)(x - 2)

y = -x^{3} -2x^{2} + 5x +6

A linear function and its inverse are given.
jarptica [38.1K]

Answer:

x: -5,  -3,   0,  1,  4

y:-23, -15, -3, 1, 13        for the function.

x:-23, -15, -3, 1, 13

y: -5,   -3,  0,  1,  4         for the inverse.

Step-by-step explanation:

we know that if we have the function f(x) = y, then the inverse of f(x) (let's call it g(x)) is such that:

g(y) = x.

now we have

y=4x-3

y=(1/4)x+3/4

The only table that works for our first function is:

x: -5,  -3,   0,  1,  4

y:-23, -15, -3, 1, 13

You can see this by replacing the values of x and see if the value of y also coincides.

Then, using the fact that the other table must be for the inverse, we should se a table with the same values, but where the values of x and y are interchanged.

The second table is that one:

x:-23, -15, -3, 1, 13

y: -5,   -3,  0,  1,  4
