Rewrite the function by completing the square.
f(x)= x^2-8x-2 f(x)=(x+ )^2+

Solve by Completing the Square x^2+8x-2=0 ... To create a trinomial square on the left side of the equation, find a value that is equal to the square of half of b b .

0 is its x and y coordinate

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
