A symmetric function is a function in several variable which remain unchanged for any permutation of the variables.
f(-x) = f(x)
Final answer
from the final solution
The answer is x².
f(x) = <span>5x - 6
</span>g(x) = x²<span> - 5x + 6
(f + g)(x) = f(x) + g(x)
= </span>5x - 6 + x² - 5x + 6
= x² + 5x - 5x + 6 - 6
= x² + 0 + 0
= x²
Answer:
A'(5, -3)
Step-by-step explanation:
Reflection over the x-axis changes the sign of the y-coordinate:
(x, y) ⇒ (x, -y)
A(5, 3) ⇒ A'(5, -3)
Answer:
15/4 <em>OR 3 whole number 3/4</em>
Step-by-step explanation:
(y2-y1)/(x2-x1)
(-12-3)/(-1-2)= -15/-3= 5
slope is 5
y=5x+b
-12=5(-1)+b
b or the y-int equals -7
therefore the equation is y=5x-7
