X^2

Answer 4

-9

Answer 5

the answer is A

Answer 6

r u sure????? kenzmyers?

Answer 7

if its right ill give the correct answer best response

Answer 8

i am positive

Answer 9

look

Answer 10

can you help me with another question?

Answer 11

kenzmyers?

Answer 12

add the two functions , i.e. f(x) + g(x) then sub in -2

f+g = x^2 + 2x -9

f+g (-2) = 2(-2) + 1 +(-2)^2 -10 = -9

Answer 13

Consider the functions f(x) = 2x + 1 and g(x) = x2 − 10. What is the value of (f + g)(−2)?

so essentially you will evaluate each individual equation and then combine the two thus being:


f: 2(-2) +1 = -3
g: (-2)^2 -10= -6

-3 + -6 =-9

Answer 14

ohh ok thks kenzmyer and fortune

Answer 15

will u help with another question?

Answer 16

Choose the best description of how to calculate f[g(3)] if f(x) = 3x − 2 and g(x) = x2 − 1.

Calculate f(3) and g(3), then multiply them together.

Calculate f(3) and g(3), then write the results as an ordered pair.

Calculate f(3) and g(3), then subtract them.

Calculate g(3), plug the result into f(x) and simplify.

Answer 17

sure

Answer 18

ok i posted it on this

Answer 19

Calculate g(3), plug the result into f(x) and simplify.

Answer 20

thanks so much!

Answer 21

Consider the functions f(x) = 2x + 1 and g(x) = x2 − 10. What is the value of f[g(3)]?

39

−3

−7

−1

Answer 22

sure

Answer 23

i chose u as best response since ur helping me the most. thks so much

Answer 24

first calculate g(3);
g(3) = 3^2 - 10 = -1

then put that into f(x) = 2x + 1
f(g(3)) = 2(-1) + 1 = -1

final answer = -1

Answer 25

I have one last question but Im going to post it as a new question so if you want to go see it and answer it ill chose u as best answer again.
