It would be Z-9 since you are subtracting 9 from Z
Answer:
(-4,6)
Step-by-step explanation:
When you reflect a point across the x and then y-axis, it is called an Origin Reflection
Origin Reflections, to put it simply, is when you have two points (a,b) and you find their opposites (-a,-b)
You have the point (4,-6)
The origin reflection of this point is (-4,6)!
Answer:
uh why not..?
Step-by-step explanation:
Answer:
ax² + bx + c
Step-by-step explanation:
The form of a quadratic equation that is easy to use when finding the maximum or minimum value of the function is ax² + bx + c.
Suppose a quadratic function:
f(x) = 2x² - 8x + 9
Use ( -b/2a , f(-b/2a) ).
-b/2a
a = 2
b = -8
-(-8)/2(2)
8/4
= 2
f(2) = 2(2)² - 8(2) + 9
f(2) = 2(4) - 8(2) + 9
f(2) = 8 - 16 + 9
f(2) = 1
The minimum value of this quadratic function is (2, 1).
It represents a minimum value because a > 0.
