Answer:
(f+g)(x) = 3x^2 + x + 1

Explanation:
We are given that:
f(x) = 3x^2 - 1
g(x) = x + 2
To find (f+g)(x), all we have to do is add the above to functions as follows:
(f+g)(x) = f(x) + g(x)
= 3x^2 - 1 + x + 2
= 3x^2 + x + 1

Hope this helps :)

Evaluate x4 + 4x3 - 2x2 + 11x - 6 for x = 3

erica [24]

Step-by-step explanation:

$f(x) = {x}^{4} + 4 {x}^{3} - 2 {x}^{2} + 11x - 6$

$f(3) = {3}^{4} + 4. {3}^{3} - 2. {3}^{2} + 11.3 - 6$

$f(3) = 81 + 4.27 - 2.9 + 33 - 6$

$f(3) = 81 + 108 - 18 + 33 - 6$

$f(3) = 198$

the admission fee for a charity event is 7 dollars for children and 10 dollars for adults the event was attended by 700 people a

ollegr [7]

Given:
$7/child
$10/adult
Total people = 700
Total money = $6,400

First, make two equations.
Let a = # of adults & Let c = # of children.
Let p = total people

1. a+c = 700
2. 10a+7c = 6,400

Then, rearrange the equation to solve for a variable.
c = 700-a

Substitute (700-a) for c, or the # of children in the second equation.
10a+(700-a) = 6400
9a+700 = 6400
9a+700-700 = 6400-700
9a = 5700
9a/9 = 5700/9
a = 633 $\frac{1}{3}$ = # of adults attended

700-633 $\frac{1}{3}$ = c = 66 $\frac{2}{3}$ = # of children attended
