Question

Which equation represents a linear function?

Equation 1: y3 = 2x + 1
Equation 2: y = 3x + 1
Equation 3: y = 5x2 − 1
Equation 4: y = 4x4 − 1

Answer 1

linear equation y = mx+b

Answer 2

so whats the answer ? @Nnesha

Answer 3

answer you have to find it
linear e equation is y = mx+b straight line
which answer choices have number or variable without any exponent

Answer 4

is it equation number 2 ?

Answer 5

yes right

Answer 7

i'll try :)

Answer 8

Which of the sets of ordered pairs represents a function?

A = {(3, −5), (4, 6), (−3, 9), (2, 7)}
B = {(2, 4), (−1, −7), (5, 6), (4, 3)}

Answer 9

In a function, nothing in the domain will repeat.

Answer 10

in order to be function
x's shouldn't repeat
if there is same value of x more than once then its not a function

Answer 11

So identify your function like that.

Answer 12

Yes what she said, lol.

Answer 13

and remember first value in order pair is x and 2nd one is y
like this (x , y ) <--- just look at x values

Answer 14

A= {(3,-5), (4,6), (-3,9), (2,7)}
B= {(2,4), (-1,-7), (5,6), (4,3)}

Answer 15

@Nnesha

Answer 16

yes i'm here :)

Answer 17

is it a ?

Answer 18

so look at A and B relation
and see which one have same x more than once

Answer 19

Actually looking at them both, it looks like both are qualified to be functions.

Answer 20

okay how is it a ??

Answer 21

im so comfused

Answer 22

Are you sure you wrote this correctly? Didn't forget a negative sign or something?

Answer 23

like i said you have too look at x values
for example this relation is not function

bec there is x repeating
