Answer:
every number is an integer
The derivative is the gradient.
At any local Max's or min's the derivative graph will cut the x axis.
For example a graph x^2
The derivative will have a positive gradient as the gradient is increasing at the lower values then at x=0 the gradient is 0 so the derivative graph will pass the point (0,0). Remember that the derivative graph will be linear.
To get more detail find the points the graph crosses the x axis and put into for a(x-q)(x-p)=0 you will have to solve for 'a' by finding a point on the graph and substituting it in. Then you can find the derivative of that function and graph it
The value of the function when x = 2 will be 9. The value is obtained by putting the value 2 in the place of x.
<h3 /><h3>What is a function?</h3>
A connection between independent variables and the dependent variable.is defined by the function. Functions help to represent graphs and equations.
The given function in the problem is;
![\rm f(x) = 2x^2 - 3x + 7](https://tex.z-dn.net/?f=%5Crm%20f%28x%29%20%3D%202x%5E2%20%20-%203x%20%2B%207)
On putting x =2 we get;
![\rm f(2) = 2(2)^2 - 3(2) + 7 \\\\\ f(2) = 2(4) - 3(2) + 7 \\\\ f(2) = 8 - 6 + 7 \\\\ f(2) = 9](https://tex.z-dn.net/?f=%5Crm%20f%282%29%20%3D%202%282%29%5E2%20%20-%203%282%29%20%2B%207%20%5C%5C%5C%5C%5C%20f%282%29%20%3D%202%284%29%20%20-%203%282%29%20%2B%207%20%5C%5C%5C%5C%20f%282%29%20%3D%208%20%20-%206%20%2B%207%20%5C%5C%5C%5C%20f%282%29%20%3D%209)
Hence the value of the function when x = 2 will be 9.

Answer:
-1/4x + 1 ( If this is wrong then ignore this)
Step-by-step explanation:
The formula for a problem like this is y - y1 = m(x - x1). The x coordinate, -8 is the x1 and the y coordinate 3 is x1. So the equation is y - 3 = -1/4(x + 8)
Equation:
y - 3 = -1/4(x + 8)
y - 3= -1/4x - 2
y = -1/4x + 1
Therefore the equation for the line is y = -1/4x + 1
8n-2n=12
subtract the n’s: 8n-2n= 6n
then divide both sides by 6: 6n/6= 12/6
the 6 with the n and the six that’s in the denominator cancel out then divide 12 by six so: n= 2
