Answer:
y = ± [ √(x+4) ] / 3
Step-by-step explanation:
1) To find the inverse of the function y = 9x2 – 4, exchange the variables x and y, and then solve for the new y.
2) Exchange of the variables: y = 9x^2 – 4 → x = 9y^2 – 4
3) Solve for y:
=> 9y^2 = x + 4
=> y^2=> y = ± [ √(x + 4) ] / 9
= > y = ± [ √(x + 4) ] / 3
Answer:
AC = 8x - 4
Step-by-step explanation:
AC = AB + BC
AC = 6x - 7 + 2x + 3
AC = 6x + 2x - 7 + 3
AC = 8x - 4
