Answer:
Step-by-step explanation:
a) x = 1.786 & -1.120
Explanation:
Turning points are points where the derivative equals zero. Solving the derivative for the values of X will give the answer to part a.
The derivative of this equation ![x^3 =x^2-6x[/t[tex] is [tex]3x^2+2x-6](https://tex.z-dn.net/?f=x%5E3%20%3Dx%5E2-6x%5B%2Ft%5Btex%5D%20%20is%20%5Btex%5D3x%5E2%2B2x-6)
.
Solving the equation 
using the quadratic formula we get 1.786 & -1.120
b) x = -3, x=0 and x=2
Explanation:
The solution to this equation are the points where the graph intersects with the x axis. Looking at the graph we can see that these points are -3 , 0 and 2
An exponent is a number written above and to the right side of a value or number in math. The value or number is called the base, and the expression is read out as;
"Base raised to the power of exponent."
An example is given below;
In this example, 10 is the base and 3 is the EXPONENT.
The expression is now read out as,
"10 raised to the power of 3"
Note that even unknown values (such x as we commonly use in math) can also be an exponent or base. For example, we can have;
So basically, an exponent indicates the number of times a number is used to multiply itself.
Pretty sure 6.5 because line CB and ZY are similar and you divide by 3 to make them similar so you divide line AB by 3 and you get 6.5
