How can you use transformations to graph this
function?
y=3•7-1+2

a) Reflection across y-axis

b) Vertical stretch by a factor of 3

c) Upward shift by 2 units

Step-by-step explanation:

The parent function for this function is 

We have to explain how the given function can be obtained from the parent function.

Let y=g(x)

So, 

Notice that x in the exponent is multiplied by -1. Multiplying x by -1 implies the reflection of the graph across y-axis.

The function value is multiplied by 3. This suggest a vertical expansion by a factor of 3.

2 is being added to the function value, this implies a vertical shift upwards by 2 units.

So, we can write:

y = g(x) = 3f(-x) + 2

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.
