Question

Medal and fan please help

1. f(x) = x2 – 4 and g(x) = x – 2
(a) What is (f + g)(x)?
(b) What is (f – g)(x)?
(c) What is (fg)(x)?
(d) What is ?

Answer 1

Medal and fan

Answer 2

do you know what mean (f+g)(x) ?

Answer 3

No can you explain the problem to me and help me solve it

Answer 4

I believe you would for

b subtract f(x)-g(x)
a. add f(x)+g(x)
c multiply the two functions together

Answer 5

how would i do that

Answer 6

f(x)+g(x)

\[x^{2}-4+(x-2) = ? \]

Answer 7

ok

Answer 8

x^2+x-6?

Answer 9

yes

Answer 10

now, for b you just subtract f(x) - g(x)

so x2 – 4 - ( x – 2 )

Answer 11

B)x2−3x−4

Answer 12

check your math

Answer 13

x^2 – 4 - ( x – 2 )

=

x^2 - 4 - x + 2 = ?

Answer 14

x2−x−2

Answer 15

good

now for part c) you just multiply

(x2 – 4)(x – 2)

Answer 16

−x3−4x+8 @Vocaloid

Answer 17

x3-2x2-4x+8 @Vocaloid
