Answer:

left: yes
right: no

Step-by-step explanation:

A function maps an x-value to a single y-value. The graph of the parabola on the left does that.

The table on the right maps -1 to both 10 and 20, so does not meet the definition of a function.

In 1 hour Samantha can make 6 beaded bracelets. In 3 hours she can make 18 bracelets. How many can she make in 4 fours? PLEASE P

Step2247 [10]

Basically Samantha makes six bracelets per hour, so:
After 1 hour she makes 6
After 2 hours she makes 12
After 3 hours she makes 18
After 4 hours she makes 24, therefor the answer is B

This can also be modelled by the equation B = 6t, where B is the number of bracelets and t is the number of hours, so:
B = 6(4) = 24

The exponential function f(x) = 2^x undergoes two transformations to

Eddi Din [679]

Option A: It is vertically stretched

Option B: it is shifted down

Solution:

The exponential function $f(x)=2^{x}$ undergoes two transformations to $g(x)=5 \cdot 2^{x}-3$ .

<u>To determine how the graph changes:</u>

Consider the given exponential function $f(x)=2^{x}$ .

Let y = f(x)

Vertically compressed or stretched:

A vertically compression (stretched) of a graph is compressing the graph toward x-axis.

• if k > 1 , then the graph y = k• f(x) , the graph will be vertically stretched by multiplying each y coordinate by k.

• if 0 < k < 1 if 0 < k < 1 , the graph is f(x) vertically shrunk (or compressed) by multiplying each of its y-coordinates by k.

• if k should be negative, the vertical stretch or shrink is followed by a reflection across the x-axis.

Here, k = 5

So the graph will be vertically stretched.

Also, Adding 3 to the graph will move the graph 3 units down so, the graph is shifted down.

So, The graph is shifted down.

Hence option A and option B is the correct answer.
