Answer 1

o.o Uh...Try copy and paste the image

Answer 2

if f(x)=1/2x^2-3 and g(x)=3x/4, evaluate F(x) divided by G(x) for x=-1

Answer 3

nope

Answer 4

@Vocaloid

Answer 5

f(x)/g(x) is simply (1/(2x^2-3)) / (3x/4)

evaluate this when x = -1

Answer 6

yup

Answer 7

@Vocaloid

Answer 8

the original notation is a bit unclear, could you take a screenshot or use the equation tool to write the original functions?

Answer 9

ok

Answer 10

is it 1/2x^2 - 3 or 1/(2x^2 -3) or something else?

Answer 11

the first

Answer 12

fractions

Answer 13

ok, so what do you get when you substitute x = -1 into 1/2x^2 - 3?

Answer 14

2? idk

Answer 15

replace "x" with "-1" and evaluate 1/2x^2 - 3

Answer 16

-5?

Answer 17

1/-5

Answer 18

(1/2)(-1)^2 - 3 = ?

Answer 19

2(-1)^2 - 3 is not -5

Answer 20

-1

Answer 21

good, so now let's evaluate g(-1)

Answer 22

g(-1)=3x/4 = 3(-1)/4 = ?

Answer 23

good, so now let's divide (1/-1) / (-3/4) = ?

Answer 24

how do you divide fractions?

Answer 25

switch the numerator and denominator of the second fraction

Answer 26

then change the division sign to a multiplication sign

Answer 27

(1/-1) / (-3/4) = -1 * (4/-3) = ?

Answer 28

-4/3?

Answer 29

almost, make sure to cancel out the - signs

Answer 30

it ends up being 4/3 (is that one of the answer choices?)

Answer 31

or is 1 1/3 an answer choice? (it's 4/3 as a mixed number)

Answer 32

yess!! thank you!
