Answer:

y=3(x-7)^2

Step-by-step explanation:

<u />

<u>Translations</u>

For a > 0

f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}

y=a\:f(x) \implies f(x) \: \textsf{stretched parallel to the y-axis (vertically) by a factor of}\:a

<u>Parent function</u>

y=x^2

<u>Translated 7 units to the right</u>

Subtract 7 from the x-value:

f(x-7) \implies y=(x-7)^2

<u>Vertically stretched by a factor of 3</u>

Multiply the whole function by 3:

3f(x) \implies y=3(x-7)^2
