Answer:
Minimum 8 at x=0, Maximum value: 24 at x=4
Step-by-step explanation:
Retrieving data from the original question:
![f(x)=x^{2}+8\:over\:[-1,4]](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E%7B2%7D%2B8%5C%3Aover%5C%3A%5B-1%2C4%5D)
1) Calculating the first derivative

2) Now, let's work to find the critical points
Set this
 
     
0, belongs to the interval. Plug it in the original function

3)  Making a table x, f(x) then compare
x|  f(x)
-1 | f(-1)=9  
0 | f(0)=8   Minimum
4 | f(4)=24 Maximum
4) The absolute maximum value is 24 at x=4 and the absolute minimum value is 8 at x=0.    
 
        
             
        
        
        
Answer:
27
Step-by-step explanation:
f(x) = 5x - 8
f(7) = 5(7) - 8 = 27

Step-by-step explanation:
y- 6 = 1/2 (x-2)
y -6 = 1/2x - 1
y = 1/2x + 5
