The correct answer is A. Plot the y-intercept (0, -1) and use the slope of one-fourth to find a second point.
Which equation defines the graph of y = x3 after it is shifted vertically 5 units down and horizontally 4 units left?
A. y = (x – 4)3 – 5
B. y = (x + 5)3 – 4
C. y = (x + 5)3 + 4
D. y = (x + 4)3 – 5
A. y = (x – 4)3 – 5
B. y = (x + 5)3 – 4
C. y = (x + 5)3 + 4
D. y = (x + 4)3 – 5
The correct answer is A. y = (x - 4)3 - 5.
