Which set represents the domain of the function shown?

{(−3, 6), (0, 2), (4, 7), (11, 15)}

{(6, −3), (2, 0), (7, 4), (15, 11)}
{2, 6, 7, 15}
{−3, 0, 4, 11}
{−3, 0, 2, 4, 6, 7, 11, 15}

Given that h(x) = 3x −19, find the value of x that makes h(x) = 71.

they are two separate questions. please help

HI!!

anonymous · Answer

hey :)

misty1212 · Answer

for the domain of $$\{(−3, 6), (0, 2), (4, 7), (11, 15)\} $$list the first numbers in each pair

anonymous · Answer

i always mix it up with the range lol. now i understand that one thank you!

misty1212 · Answer

for the second one, solve $$3x-19=71$$

anonymous · Answer

and then that will be the answer?

misty1212 · Answer

add 19 and then divide by 3
what do you get ?

anonymous · Answer

30

misty1212 · Answer

yup

anonymous · Answer

thank you! could you help me with a few more? @misty1212

misty1212 · Answer

sure

anonymous · Answer

Choose the equation of the horizontal line that passes through the point (2, 4). 
 	
	y = 2
	x = 2
	y = 4
	x = 4

Write the equation of the line that passes through the points (3, 6) and (5, 18) using function notation. 
 	
	f(x) = 2x + 12
	f(x) = 6x − 12
	y = 2x + 12
	y = 6x − 12

Choose the equation below that represents the line that passes through the point (7, −2) and has a slope of −3. 
 	
	y − 2 = −3(x + 7)
	y + 7 = −3(x − 2)
	y + 2 = −3(x − 7)
	y − 7 = −3(x + 2)

Choose the equation of the horizontal line that passes through the point (2, 4).
horizontal line looks like $y=\text{something}$
in this case the "something" is 4

anonymous · Answer

y = 4?

misty1212 · Answer

yes

anonymous · Answer

yay!! ok :)

misty1212 · Answer

Write the equation of the line that passes through the points (3, 6) and (5, 18) using function notation. 
slope is $\frac{18-6}{5-3}=\frac{12}{2}=6$

misty1212 · Answer

$$	f(x) = 6x − 12$$is the only choice written in function notation

anonymous · Answer

oh ok that makes sense :)

misty1212 · Answer

Choose the equation below that represents the line that passes through the point (7, −2) and has a slope of −3. 
 	
point slope formula $$y-y_1=m(x-x_1)$$ in this case $$y+2=-3(x-7)$$
