Answer:
vertically stretched by a factor of 5
Step-by-step explanation:
Multiplying the function value by 5 makes each vertical coordinate 5 times the value it was, so it is 5 times as far away from the x-axis. This has the appearance of stretching the graph vertically by a factor of 5.

Comment on the answer choices
The stretch factor is a "pure number", a ratio of new units to old units. It is "5", not "5 units."
For example, if f(x) is 1 ft (1 unit, where the unit is a foot), then g(x) = 5 ft, the value of f(x) multiplied by 5. It is not 5 ft^2, as you would get if f(x) were multiplied by 5 units, or 5 ft.
It is 4 1/2. If you keep the first number switch the division symbol into a multiplication sign and find the reciprocal of the last number you would get this.
Answer: cheese pizzas = 25 , Pepperoni pizzas = 15
Step-by-step explanation:
Let x = Number of cheese pizzas, y = Number of pepperoni pizzas.
As per given,
Multiply 7 on both sides of (i), we get
Eliminate (iii) from (ii), we get
Put value of y in (i) , 
Hence, cheese pizzas = 25 , Pepperoni pizzas = 15
73 lb 9 oz is 1177 oz
38 lb 14 oz is 622 oz
1177-622= 555
555/16
34 . 6875
.6875 of a lb is 11 oz
The final answer is 34 lb and 11 oz
