Answer:

Shift 1 units towards left and then stretch vertically 3 times.

Explanation:

We are given that a parent function


y=x^2

After transformation, we get a graph
y=3(x+1)^2

We have to find that how the parent function transformed to produce the graph of
y=3(x+1)^2

The parent graph is shifted 1 unit towards left by the rule of transformation


f(x)\rightarrow f(x+1)

By applying this rule then, we get


y(x)=(x+1)^2

Now, the parent function stretched vertically 3 times the previous graph by the rule


f(x)\rightarrow 3f(x)

Apply this rule then, we get


y(x)=3(x+1)^2
