Answer:
look below
Step-by-step explanation:
y = 2 (x + 3)^2 - 2
Geometric figure: parabola
Alternate forms:
y = 2 (x + 2) (x + 4)
y = 2 (x^2 + 6 x + 8)
-2 x^2 - 12 x + y - 16 = 0
Expanded form:
y = 2 x^2 + 12 x + 16
Roots:
x = -4
x = -2
<u>Properties as a real function:
</u>
Domain
- R (all real numbers)
Range
- {y element R : y>=-2}
Partial derivatives:
d/dx(2 (x + 3)^2 - 2) = 4 (x + 3)
d/dy(2 (x + 3)^2 - 2) = 0
Implicit derivatives:
(dx(y))/(dy) = 1/(12 + 4 x)
(dy(x))/(dx) = 4 (3 + x)
Global minimum:
min{2 (x + 3)^2 - 2} = -2 at x = -3
Answer:Jane is 16.5in. taller than Jim.
Step-by-step explanation:
Step-by-step explanation:
what do we need to do ?
just calculate the value of the expression by using the given values for the variables ?
what's the problem ? this is just basic calculation.
8/4 + 7×9 = 2 + 63 = 65
remember (please, for your life !) that multiplication and division always happens before any addition or subtraction (except for the case, where brackets force us in a different direction).
Answer:
34, 50
Step-by-step explanation:
An amount divide by 17: 34÷17=2
25 less than x: 50-25=25
