Does this table represent an exponential function? x 1 2 3 4 y 4 16 64 256
4vir4ik [10]

Answer:

Yes, the given table represent an exponential function.

Step-by-step explanation:

Given table is :

x y

1 4

2 16

3 64

4 256

Now we need to identify if the given table represent an exponential function or not. To find that we need to check if we can write the numbers in y-column in form of exponential function y=ab^x.

We see that y-values are basically powers of 4 so we can write the related function as y=4^x.

Which is clearly in form of y=ab^x.

Hence yes, the given table represent an exponential function.

Multiply (x - 4)(2x + 3) using the foil method show the foil method products
AVprozaik [17]

(x - 4)(2x + 3)

Using foil:

2x^2 + 3x - 8x - 12

Simplify.

2x^2 - 5x - 12 is the product after using FOIL.

Answer:

$13087.92

formula: ab^x

a= starting  amount

a= 5072

b= 1+r

r=rate

r=9%=0.09

b=1+0.09 =1.09

x= 11 (years)

account after 11 years:

= 5072(1.09)^11

=13087.9227277

Which points are on a graph where y varies directly with x and y = 3 when x = -3
kondor19780726 [428]

A coordinate system is a method of determining the position of points or other geometric components on a manifold. The points which vary are on a graph where y varies directly with x are (-1, 1), (0, 0), and (-5, 5).

<h3>What are coordinates?</h3>

A coordinate system is a method of determining the position of points or other geometric components on a manifold, such as Euclidean space, by using one or more integers, or coordinates.

Given that y varies directly with x, therefore, we can write,

y∝x

y = kx

Also, y=3 and x=-3, therefore, the value of k can be written as,

3=k(-3)

k=-1

Now, the points which vary are on a graph where y varies directly with x are (-1, 1), (0, 0), and (-5, 5).
