Question

Which function is a linear function?

1 − 3x2 = -y
y + 7 = 5x
x3 + 4 = y
9(x2 − y) = 3
y − x3 = 8

Answer 1

highest power of 1 on the independent variableeee

Answer 2

huh

Answer 3

only one has a power of 1 , the others are polynomials, not linear

Answer 4

i know i think

Answer 5

so its C

Answer 6

x3 + 4 = y

Answer 7

yeah it's c

Answer 8

y = x^3 + 4 is a polynomial, not linear

Answer 9

question?

Answer 10

should a linear function start with Y

Answer 11

shouldn't it?

Answer 12

remember a line has a form Ax+By=C , or y = m*x+b,

the highest power on x or the y is 1, no larger

Answer 13

wat are examples of nonlinear

Answer 14

polynomials are

y = ax^n + bx^(n-1) ..... c^x + d


powers larger than 1 are not lines

Answer 15

ight here is a nother ?

Answer 16

notice the second choice is the only one that has a highest power of 1, the others are greater

Answer 17

In the coming year, a vehicle manufacturer has decided to manufacture 150 vehicles per day. The function v = 150d represents the company’s production for the coming year, v, with respect to the number of days, d.

The rate of change of the function representing the number of vehicles manufactured for the coming year is , and its graph is a . So, the function is a function.

Answer 18

if a function has a constant rate of change (slope) all the time, it is a line

Answer 19

notice as before, the highest power is 1

v = 150*d

linear y = m*x + b, rate of change is the slope,m

Answer 20

is it a straight line
