Answer:

D = {–3, –1, 1, 2}; R = {–3, 1, 2, 4}

Step-by-step explanation:

We need to understand what is the domain of a function?

The domain is the set of all possible x-values which will make the function "work"

We need to understand what is the range of a function?

the range of the function is the set of all values that f(x) = y takes.

In your question,

all possible x-values : {–3, –1, 1, 2}
all possible y-values : {–3, 1, 2, 4}

So, the domain and range of the following relation is C

D = {–3, –1, 1, 2}; R = {–3, 1, 2, 4}

What will be the units of the square of the following a - 2346 b - 5677

AlladinOne [14]

<h2>Answer:</h2>

(a) 6

(b) 9

<h2>Step-by-step explanation:</h2>

The units of a whole number is the rightmost digit in the number. For example, if the number is 15678, the units is 8 since that is the rightmost digit. Another example is 25795. The units is 5.

(a) To find the units of the square of -2346,

i. First find the square of (-2346)

(-2346)² = (-2346) x (-2346) = 5503716

ii. Now find the rightmost digit.

The rightmost digit of 5503716 is 6.

Therefore, the units of the square of (-2346) is 6

(b) To find the units of the square of -5677,

i. First find the square of (-5677)

(-5677)² = (-5677) x (-5677) = 32228329

ii. Now find the rightmost digit.

The rightmost digit of 32228329 is 9.

Therefore, the units of the square of (-5677) is 9

Determine the slope of the line containing the points (-5,4) and (0,7).

bekas [8.4K]

Slope (m) = y2-y1 / x2-x1
m = 7 - 4 / 0 + 5
m = 3 / 5

In short, Your Answer would be 3/5

Hope this helps!

A golf player is trying to make a hole-in-one on the miniature golf green shown.

Flauer [41]

The path of the ball is an illustration of absolute equation.

The equation of the path is: $y =- \frac{12}7|x- 4.8| + 6.4$

The given parameters are:

$(h,k) = (4.8,6.4)$ --- the vertex (i.e. the point where the ball hits the wall)

$(x_1,y_1) = (2,1.6)$

$(x_2,y_2) = (7.6,1.6)$

An absolute function is represented as:

$y = a |x - h| + k$

Substitute $(h,k) = (4.8,6.4)$

$y = a |x - 4.8| + 6.4$

Substitute $(x_1,y_1) = (2,1.6)$ for x and y

$1.6 = a|2 - 4.8| + 6.4$

$1.6 = a|- 2.8| + 6.4$

Remove absolute bracket

$1.6 = 2.8a + 6.4$

Collect like terms

$2.8a = -6.4+1.6$

$2.8a =- 4.8$

Solve for a

$a =-\frac{4.8}{2.8}$

Simplify

$a =-\frac{12}{7}$

Substitute $a =-\frac{12}{7}$ in $y = a |x - 4.8| + 6.4$

$y =- \frac{12}7|x- 4.8| + 6.4$

Hence, the equation of the path is: $y =- \frac{12}7|x- 4.8| + 6.4$

See attachment for graph that models the path
