For the function f defined b f(x)=x^2+2x+3 find f(-x), -f(x), and -f(-x).

need pls pls 100 pnts

see explanation

Step-by-step explanation:

To evaluate f(- x) substitute x = - x into f(x)

f(- x) = (- x)² + 2(- x) + 3 = x² - 2x + 3

- f(x) = - (x² + 2x + 3) ← distribute parenthesis by - 1

       = - x² - 2x - 3

- f(- x) ← substitute f(- x) from above

= - (x² - 2x + 3) ← distribute parenthesis by - 1

= - x² + 2x - 3

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

10 you would take 50/ .2
