What transformations of the parent graph of f(x) = √x produces the graph of K(x) = √4x + 12 – 1? Select all that apply. A. The graph of k is a translation of the graph of f down 1 unit and left 12 units.

B. The graph of k is a translation of the graph of f down 1 unit and left 3 units.

C. The graph of k is a vertical stretch of the graph of f by a factor of 4.

D. The graph of k is a vertical stretch of the graph of f by a factor of 2.

answer

the correct answer is

explanation

the given function is

the excluded values are obtained by solving:

we factor to obtain:

the excluded values are

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
