Answer:
x. = sqrt 6 and x = - sqrt 6
Step-by-step explanation:
x^4 + 2x^2-48=0
(x^2 - 6) (x^2 + 8) = 0
x^2 - 6 = 0
x = + sqrt 6 and x = - sqrt 6
x^2 + 8 = 0
x^2 = sqrt -8 (a negative number doesn’t have a real square root)
It would be t plus t equals m
Answer:
6
Step-by-step explanation:
Do rise over run (change in y over change in x)
= 6
The slope is 6
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.
