Question

Literally please help i’m struggling on this

Answer 1

The output values for each of the given functions include the following:

5. f(-6) + 17 = -6

6. g(1) - 9 = 1

7. f(8) + g(-1) = 15

8. 12 - 2[g(3)] = -68

In Mathematics and Geometry, a function defines and represents the relationship that exists between two or more variables in a relation, table, ordered pair, or graph.

Next, we would determine the corresponding output value for f(x) and g(x) in simplified form as follows;

5. f(-6) + 17

f(-6) + 17 = 3(-6) - 5 + 17

f(-6) + 17 = -18 - 5 + 17

f(-6) + 17 = -6

Part 6.

g(1) - 9

`g(1) - 9=2(1)^2+7(1)+1-9\\\\g(1) - 9=2+7+1-9`

g(1) - 9 = 1

Part 7.

f(8) + g(-1)

`f(8) + g(-1)=3(8)-5 +2(-1)^2+7(-1)+1\\\\f(8) + g(-1)=24-5+2-7+1`

f(8) + g(-1) = 15.

Part 8.

`12 - 2[g(3)]=12-2[2(3)^2+7(3)+1]\\\\12 - 2[g(3)]=12-2[18+21+1]\\\\12 - 2[g(3)]=12-36-42-2`

12 - 2[g(3)] = -68
