What is the domain of the function in this table

never [62]

Option A:

{3, 4, 5, 6}

Solution:

In the given table X column have 3, 4, 5, 6 and Y column have 4, 4, 2, 5.

The domain is the set of all values for which the function is defined.

The domain of the function is set of all X values.

Option A: {3, 4, 5, 6}

Set of all X values {3, 4, 5, 6}.

It is correct.

Option B: (3, 4), (4, 4), (5, 2), (6, 5)

Here, the given values are ordered pairs of domain and co-domain.

It is not correct.

Option C: (3, 4)

Here, (3, 4) is a ordered pair of domain and co-domain.

It is not correct.

Option D: {2, 4, 5}

Here, {2, 4, 5} are values of co-domain.

It is not correct.

Hence {3, 4, 5, 6} is the domain of the function.

18)Let f(x) = -3x + 4 and g(x) = 8x2 - 9. Find g(4) - f(4) . A)140 B)127 C)131 D)136

vazorg [7]

Answer: -127

Step-by-step explanation:

They are giving you the corresponding x value for which you should plug into the function. So plug 4 into g(x) and plug 4 into f(x). Then subtract them

g(x) = -3(4) + 4 = -8

Im assuming that is $8x^2$

f(x) = 8(4)^2 - 9 = 119

Now do -8 - 119 to get -127

[(-4)+{8÷(-4)}]*(-5)^2-9 the answer is -159 just need the steps.

marishachu [46]

PEMDAS (right to left) (Parentheses, exponents, Multiplication/Division, Addition/Subtraction) or Please Excuse My Dear Aunt Sally is what I was taught to use.
1.[(-4)+{-2}]*(-5)^2-9; divide 8 by -4 (it is the innermost parentheses problem)
2. [(-6)]*-5^2-9; next innermost parentheses problem
3. [(-6)]*25-9; exponents
4. -150-9; multiplication
5. -159; subtraction/addition depending on how you want to look at it

HELP PLZZ 17 points!!!??? Kevin ran 4 miles more than Steve ran. The sum of their distances is 26 miles.

Tresset [83]

Answer:

Kevin ran 4 miles and Steve ran 22

Step-by-step explanation:

kevin: 4

Steve: (22) but for now it's x

I dont really understand what Part A. is asking

26 - 4 = x (steve) | Part B.

x (steve) = 22 | Part C.

Kevin ran 4 miles and Steve ran 22 | Part D.
