Find the coordinates for the vertex of the graph of the function y = 2x' + 2x - 4.

(-1/2,-9/2)

Step-by-step explanation:

that is the coordinates for the vertex of the function y=2xsqaured+2x-4

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
