Use the quadratic function f(x) = 2x2 + 4x +3 to answer the following questions.
1 answer:
The vertex is (-1,1) Explanation The vertex formula to find the x coordinate of the formula is -b/2a So we plug in the values into the formula which is -4/2(2) Simplify it -4/4 =-1 -1 is now the x cord of the vertex. So now we will plug in the x into the quadratic equation which is 2x^2+4x+3 2(-1)^2 + 4(-1) + 3 = 2 -4 +3 Simplify it 5 - 4= 1 Y=1 So the Coordinates of the vertex is (-1,1)

Answer:
144 pages
Step-by-step explanation:
3 hours * 60 = 180 minutes
40 pages / 50 minutes = x pages / 180 minutes
40/50 = x/180

50x = 40 * 180
50x = 7200
x = 7200 ÷ 50
x = 144
