I’m not sure what you mean but here’s what I think:
• f(x) is basically another use for “y”.
• f(7): 7 is the “x” variable that is put into the equation. Because the original form is “f(x)”, we know that with 7 in place of “x”, 7=x.
Step-by-step explanation:
→ 8 + 4 = 2(x -1)
→ 12 = 2x - 2
→ 2x - 2 = 12
→ 2x = 12 + 2 = 14
→ x = 14/2 = 7
→ x = 7
hence, option D (7) is correct.
Hope this answer helps you dear ! take care
