Question

Describe the transformation of the parent function.

Question 5 options:

The parent function shifted up 2 units


The parent function shifted right 2 units


The parent function shifted down 2 units


The parent function shifted left 2 units

Answer 1

The parent function shifted right 2 units

Explanation:

When functions are transformed there are a few simple rules:

• Adding/subtracting inside the parenthesis to the input shifts the function left(+) and right(-).

• Adding/subtracting outside the parenthesis to the output shifts the function up(+) and down(-).

• Multiplying the function by a number less than 1 compresses it towards the x-axis.

• Multiplying the function by a number greater than 1 stretches it away from the x-axis.

The square root graph normally starts at (0,0) but on the graph it starts at (2,0). This means it has moved 2 units to the right.
