Answer:
Step-by-step explanation:
y²-x⁴
y=9, x=2
9²-2⁴ = 81-16 = 65
Left and right affect domain. (x)
Up and down effects range. (y)
So,
-2+5 (because the right of the number line is an increase)
7-2 (because you are decreasing by going down)
You are left with:
R'(3,5)

Taking into account the repeated ones it would be 7! what is 7*6*5*4*3*2*1
Answer:
x^2 - 2x + 5 = 0.
Step-by-step explanation:
The (0, 5) is the point where the parabola passes through the y axis (where x = 0), so we can write the equation as
y = ax^2 + bx + 5 where a and b are constants to be found.
Also, since (1, 4) and (2, 5) are points on the curve, substituting, we have the system:
a(1)^2 + 1b + 5 = 4
a(2)^2 + 2b + 5 = 5
Simplify these 2 equations:
a + b = -1 .................(1)
4a + 2b = 0..................(2)
Multiply the first equation by -2:
-2a - 2b = 2 .................(3)
Add (2) + (3):
2a = 2
a = 1.
Substitute a = 1 into (2):-
4*1 + 2b = 0
2b = -4
b = -2.
