Answer:
exponential
Step-by-step explanation:
The exponential function has the largest value for large values of x. Here, "large" means "greater than 4.3". A graph shows this to be true.
For x=10, the exponential function will have a value of 2^10 = 1024.
The quadratic function will have a value of 10^2+1 = 101.
The linear function will have a value of 10+1 = 11.
The exponential function has the largest value.
(x+9)(x+8) = x^2 +17x + 72
(x- 7)(x+8) = x^2 + x - 72
(x- 5)(x- 6) = x^2 -11x + 30
(2x + 3)(3x+2) = 6x^2 + 13x +6
(5x - 4)(2x-5) = 10x^2 - 33x + 20
(x-4)^2 = x^2 -8x + 16
(2x+1)^2 = 4x^2 +4x + 1
(4x+3)(4x-3) = 16x^2 - 9
Y = kx, k being a constant
--------------------------------------
Find k :
--------------------------------------
When x = 12, y = 3
3 = k(12)
k = 3/12
k = 1/4
Equation : y = 1/4 x
--------------------------------------
Find y when x = 20:
--------------------------------------
When x = 20,
y = 1/4 (20)
y = 5
--------------------------------------
Answer: y = 5
--------------------------------------
-0.127
-0.12
0.20
0.33
45/10
I think that is right
