Answer:
i think 2. is : 1and 3. is
Step-by-step explanation:
X² + 2x +3
If the discriminent Δ = b²-4.a.c <0 , that means the roots (or the zero value) are nit REAL Number (they are imaginary or complex)
Δ = 2² - 4(1)3) = 4 - 12 = -8
since Δ = - 8 < 0 there are no real roots
Answer:
The average velocity of the ball is 
Step-by-step explanation:
First find the velocities at given times and then form two points. Calculate the slope to find the average velocity. The two points are:

Answer:
1.26 but rounded to the nearest 10 would be 1.3 so 1.3 is your answer
Step-by-step explanation:
Answer: Y=1/2+2
Why? You find the slope of the line but picking one point the intersects directly on a point then rise up and over to find the next point that intersects directly on a point so I used point 0,2 and rise 1 and over 2 to get to point 2,3.
Slope= rise/run so it’s 1/2
And the last number in the equation is the y intercept because Y=mx+b
M=slope
B= y intercept
The y intercept is 2
Hope this helps (if I need to explain better just comment on this and I can try)
