Find the invers of f(x)
f(x) = 2x - 6
y = 2x - 6
y + 6 = 2x
2x = y + 6
x = (y + 6)/2
f⁻¹(x) = (x + 6)/2
Solve f⁻¹(x) for x = 2
Subtitute x with 2
f⁻¹(x) = (x + 6)/2
f⁻¹(x) = (2 + 6)/2
f⁻¹(x) = 8/2
f⁻¹(x) = 4
The answer is 4
B is the answer
Hope this helps.
D. You need the data values to figure it out
20% off original price that is $25
so 0.20 * 25 = 5
so that means that the new price is $20
you save $5
Answer:
90
Step-by-step explanation:
we have:
9*(7-4)^2+9
we subtract 7 and 4: 7-4
we have:
9*(3)^2+9
we know: 3^2=3*3=9
so we have:
9*9 +9
we multiply 9 by 9: 9*9 = 81, so we have:
81+9
90
