2. What is the equation, in standard form, of a parabola that models the values in the table?
2) Enter values into each equation to test if f(x)=y.
0=6(-2)^2+5(-2)-4
0=6(4)-10-4
0=24-14
0 is not equal to 10, so this equation does not work.
0=-4(-2)^2+5(-2)+6
0=-4(4)-10+6
0=-16-16
0 is not equal to -32, so this equation won’t work either
0=5(-2)^2+4(-2)-6
0=5(4)-8-6
0=20-8-6
0 is not equal to 14 so this equation is also false
0=4(-2)^2+5(-2)-6
0=4(4)-10-6
0=16-16
This equation works, all you have to do is write it in a standard form.
4x^2+5x-6=0
3) This one works the same way.
635=33(0)^2-24(0)+635
635=0-0+635
It works, but let’s try another combination just to be sure.
644=33(1)^2-24(1)+635
644=33-24+635
644=644
Now we just need to enter 8 to see what we find.
P(8)=33(8)^2-24(8)+635
P(8)=33(64)-192+635
P(8)=2112-192+635
P(8)=2555 aquatic birds
4) Your answer is correct. The total time from when you throw the ball to when it hits the ground is 8 seconds, so that’s the pinnacle of mastery. Obviously the low point will be zero because the timer starts as soon as the ball leaves your hand.
