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

Step-by-step explanation:

Answer:
5 and 7.
Step-by-step explanation:
Hey! So to start you need to create an algebraic expression. You can express this problem through the following equation:
*Note: if x is an odd integer, x + 2 is the next consecutive odd integer.

Expanding, you get:

And moving the 35 to the other side, you get a simple quadratic.

Solving by factoring:

This means two possible solutions for the smaller consecutive number are -7 and 5. However the question asks for two positive odd integers, so one of the numbers must be 5. The next will be 7(as its x + 2).
89 squared. The hypotenuse is equal to 9.434 which is 89 squared.
