Answer:
f(x) = -5/3x + 5/3
Step-by-step explanation:
if x = 4 ; f(x) = -5
if x = -2 ; f(x) = 5
f(x) = ax + b
-5 = 4a + b <em>(</em><em>1</em><em>)</em><em> </em>
and
5 = -2a + b <em>(</em><em>2</em><em>)</em>
<em>(</em><em>1</em><em>)</em><em> </em><em>+</em><em> </em><em>(</em><em>2</em><em>)</em><em> </em>
2a + 2b = 0
a = -b
<em>(</em><em>1</em><em>)</em><em> </em>-5 = 4a - a
-5 = 3a
a = -5/3

f(x) = -5/3x + 5/3
Either positive or negative 180°.
Answer:
Profit of 532
Step-by-step explanation:
Since the SP is more than the CP then there is a profit
profit = SP - CP = 832 - 300 = 532
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
