We have the parent function:
y = x³ and we have to choose the correct answer to the question: which equation describes how is this function vertically stretched by a factor of 4.
y = x³ + 4 → The parent function is moved vertically 4 units up.
y = ( x + 4 )³ → The parent function is moved horizontally 4 units left.
y = x^4 → This is a different function.
Answer:
C ) y = 4 x³.

Explanation:
A)
Let t and f represent the numbers of two-point and four-point questions, respectively.
__
B) The number of points for each type of question is the product of the point-value per question and the number of questions of that type.
2t + 4f = 100 . . . . . the test is worth 100 points
t + f = 40 . . . . . . . . there are 40 questions on the test
_____
<em>Additional comment</em>
The test will have 30 two-point questions and 10 four-point questions.
