Question

Identify the quadratic function(s). (Select all that apply).

y(y + 4) - y = 6

(3x + 2) + (6x - 1) = 0

4b(b) = 0

3a - 7 = 2(7a - 3)

Answer 1

quadratic means the "variable" has an exponent of 2
the highest exponent must be 2, and there has to be at least one term with an exponent of 2.

Answer 2

?

Answer 3

start with this one
(3x + 2) + (6x - 1) = 0

what is the exponent on the "x" ? any idea ?

Answer 4

I don't know how to do these.

Answer 5

do you know that
\( x^2 \) means x*x ?

Answer 6

yes

Answer 7

also
\[ x^1 = x\]
usually we don't bother to write the exponent of 1
but we can put it in

Answer 8

exponent means the little number we put in the upper right of the x

Answer 9

I got it now thanks

Answer 10

now look at
3x + 2

the "x" has an exponent (if we write it). what is it ? any idea ?
