Answer:
Step-by-step explanation:
-5x - 7 ≤ 2
+ 7 ≤ +7
---------------
-5x ≤ 9
---- -----
-5 -5
X=-1.8
-5(-1.8)-7 ≤ 2
First, you need to find the derivative of this function. This is done by multiplying the exponent of the variable by the coefficient, and then reducing the exponent by 1.
f'(x)=3x^2-3
Now, set this function equal to 0 to find x-values of the relative max and min.
0=3x^2-3
0=3(x^2-1)
0=3(x+1)(x-1)
x=-1, 1
To determine which is the max and which is the min, plug in values to f'(x) that are greater than and less than each. We will use -2, 0, 2.
f'(-2)=3(-2)^2-3=3(4)-3=12-3=9
f'(0)=3(0)^2-3=3(0)-3=0-3=-3
f'(2)=3(2)^2=3(4)-3=12-3=9
We examine the sign changes to determine whether it is a max or a min. If the sign goes from + to -, then it is a maximum. If it goes from - to +, it is a minimum. Therefore, x=-1 is a relative maximum and x=1 is a relative miminum.
To determine the values of the relative max and min, plug in the x-values to f(x).
f(-1)=(-1)^3-3(-1)+1=-1+3+1=3
f(1)=(1)^3-3(1)+1=1-3+1=-1
Hope this helps!!
Slope intercept form is y = mx+ b
So in order to turn 5y-3x + 20 = 0 into Slope intercept form, all we need to do is solve for y!
Let's do it!
- add 3x to the right side of the equation
<u>5y - 3x + 20 = 0</u>
<u>5y + 20 = 3x </u>
- move 20 to the right side
<u>5y = 3x - 20 </u>
- Divide both sides of the equation by 5
y = 3/5x - 4
This is our answer!
I hope I helped! Leave a comment if you have any questions or concerns
