Question

use f(x)=x^2 and g(x)=x+5. Find the function and simplify the function rule.

(f o g)(x)

Answer 1

@Nnesha @triciaal

Answer 2

f o g(x) use the value for g(x) as x in f(x)

Answer 3

so f(g(x)) ----> f(x+5). do i multiply f(x) to the g(x)?

Answer 4

think about it as this \(f(x)=x^2\)
i can replace that x with something else like \(f(\square)=(\square)^2\)
so \(fog(x)=f(g(x))=(g(x))^2\)

Answer 5

f(x)=x^2 and g(x)=x+5.
f(x) = x^2 and x = (x + 5) so it becomes (x + 5)^2

Answer 6

so i get x^2+25?

Answer 7

incomplete try again multiply each term

Answer 8

Not quite!
recall that \((a+b)^2=a^2+2b+b^2\)

Answer 9

forgot a in there
