Question

What is the resulting ordered pair if the value of the independent variable is -1/2

f(x)=12x^2-8x

answer choose:
A- [-1/2,-1]
B- [-1/2,7]
C- [-7,-1/2]
D- [7,-1/2]

Answer 1

@ganeshie8 please help

Answer 2

the independent variable is \(\large x\)

Answer 3

yea?

Answer 4

plugin \(\large x = -1/2\) and evaluate the function

Answer 5

\(\large f(x) = 12x^2 - 8x\)

\(\large f(-1/2) = ?\)

Answer 6

[f(-1/2)=-3+4 \]

Answer 7

right? @ganeshie8

Answer 8

you should get 3+4
because 12(-1/2)^2 = 12(1/4) = 3

Answer 9

so the y coordinate is 7

Answer 10

and the x coordinate is -1/2

Answer 11

an ordered pair is written as \(\large (x, y)\)

Answer 12

so it would be B?

Answer 13

Yes!

Answer 14

thank you so much! !!!!
