Functions: Graphing Functions Practice MCQ

Question Statement:

Transform the following parabola: $x^{2} + 4$ .

Shift up 5 and to the left 3.

(x - 3)^{2} + 9

(x + 3)^{2} - 1

(x - 3)^{2} - 1

(x + 3)^{2} + 9

x^{3} + 9

Explanation:

Correct Answer: D

When transforming paraboloas, to translate up, add to the equation (or add to the Y).

To translate to the left, add to the X.

Don't forget that if you add to the X, then since X is squared, the addition to X must also be squared.

$x^{2} + 4$ with the shift up 5 becomes: $x^{2} + 4 + 5 = x^{2} + 9$

Now adding the shift to the left we get:

$x^{2} + 9 \to (x - - 3)^{2} + 9 = (x + 3)^{2} + 9$

You are taking Aptitude Test No. 3

Each aptitude test is comprised of 10 except the last test which might have fewer than 10 in some topics.

You are at question (MCQ) number 5 and Test Number 3 of Functions: Graphing Functions. To deal with Functions questions, you must take lesson on the subject. In case of science and Art subjects revise your text books and in case of general aptitude topics take lessons from the topic page.

The question:

Transform the following parabola: $(x - 3)^{2} + 9$ , $(x + 3)^{2} - 1$ , $(x - 3)^{2} - 1$ , $(x + 3)^{2} + 9$ can be solved with the concepts and understanding of Functions.
