D. p = 3 + f
3 answers
B. p = 3f
What are the values of the function y = 3x – 4 for x = 0, 1, 2, and 3?
A. −4, −1, 2, 5
B. 0, 3, 6, 9
C. −4, 2, 5, 8
D. 0, 1, 5, 9
A. −4, −1, 2, 5
B. 0, 3, 6, 9
C. −4, 2, 5, 8
D. 0, 1, 5, 9
A. −4, −1, 2, 5
To find the values of y, we substitute each value of x into the function:
When x = 0, y = 3(0) - 4 = -4
When x = 1, y = 3(1) - 4 = -1
When x = 2, y = 3(2) - 4 = 2
When x = 3, y = 3(3) - 4 = 5
Therefore, the values of the function for x = 0, 1, 2, and 3 are −4, −1, 2, and 5 respectively.
