HELP ASAP! Will name brainiest! Given f(x) = x2 + 6 and g(x) = x − 3, identify (fg)(x).
x3 − 3x2 − 6x − 18
x3 − 3x2 + 6x − 18
x3 − 3x2 − 6x + 18
x3 + 3x2 − 6x + 18

Given f(x) = 2x2 − 3 and g(x) = x + 8, identify g(f(4)).

idk

step-by-step explanation:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
