F(x) =3x; g(x) = 4x^2 +1 which expression is equal to (fog) (x)? a 4x^2 + 3x -1 b 12x^3 + 3x c 36^2 + 1 d 12x^2 + 3 will mark brainliest

d 12x^3 + 3

Step-by-step explanation:

This is a composite function. Just insert g(x) into the x of f(x)

f(x) = 3x

3(4x^2 + 1)

Distribute the three

3(4x^2 + 1)

12x^3 + 3

i can you answer this question sweetie!

step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
