Answer:

B)y=2x   and     C) y=-7x+9

Step-by-step explanation:

Once a linear function has a constant rate of change, you just have to find the linear functions. Also, the other ones are quadratic functions, and their graph are parabolas, which don't have a constant rate of change.

Considering f(x)=y

f(x) = 2x  has a constant positive rate of slope 2.  

$\frac{dy}{dx}=2 $

f(x)=-7x+9 has a constant negative rate of slope -7

$\frac{dy}{dx}=-7 $

Suppose that F(x) = x3 and G(x) = -2x^3 - 7. Which statement best compares the graph of G(x) with the graph of F(x)?
Black_prince [1.1K]
Answer: Choice C) 
Stretched vertically, flipped over x axis, shifted 7 units down

------------------------------------------------

Explanation:

Going from y = x^3 to y = 2x^3 means the graph is pulled vertically so that each (x,y) point has the y coordinate that is doubled. Example: (1,1) turns into (1,2). If this applies to all the points, then the graph is stretched vertically by a factor of 2

Going from y = 2x^3 to y = -2x^3 flips the graph over the y axis. For example, the point (1,2) flips to (1,-2). The x coordinate stays the same with the y coordinate flipping in sign.

The last transformation is the shifting 7 units down which is taken care of by the "-7" tacked at the end. Essentially we subtract 7 from each y coordinate. Example: (1,-2) becomes (1,-9)

Eddi Din [679]
20,000 = P ( 1 + 0.1 )^4
20,000 = P * 1.1^4
20,000 = P * 1.461
P = 20,000 : 1.461 ≈ $13,689.25
Answer: Miranda needs to put now in the bank $13,689.25
