The value of the function 1) f -g = 2x² - 3x + 6 and 2) f(g(2)) is 3.
Here the two functions are given, f(x) and g(x).
f(x) = 2x² + 1
g(x) = 3x - 5
We have to find f-g and f(g(2)).
1) f- g
f(x) - g(x)
(2x² + 1) - ( 3x - 5)
2x² + 1 - 3x + 5
2x² - 3x + 6
2) f(g(2))
f(g(x)) = 2(3x-5)² + 1
= 2( 9x² - 30x + 25) + 1
= 18x² - 60x + 50 + 1
= 18x² - 60x + 51
f(g(2)) = 18(2)² - 60(2) + 51
=18× 4 - 120 + 51
= 72 - 120 + 51
= 123 - 120
= 3
Therefore the value of f-g is 2x²- 3x + 6 and the value of f(g(2)) is 3.

Answer:
Step-by-step explanation:
94
Mean = add all the numbers up and divide by how many numbers you added
So add (x +120 + 112 + 130 + 128 + 124 ) divided by 6 =118
x is the score you are looking for and 118 is the average he wants
so (x + 614 ) divided by 6 =118
now multiply both sides by 6
x + 614 = 118 times 6
x + 614 = 708
subtract 614 from both sides
x = 94
