F⁻¹(x) stands for the invers of function f(x). The inverse of f(x) is equal to x. We need to solve for x.
solve for x
f(x) = 2x + 2
2x + 2 = f(x)
2x = f(x) - 2
x =
f⁻¹(x) =
Determine the value of f⁻¹(x) when x = 4
f⁻¹(x) =
f⁻¹(4) =
f⁻¹(4) =
f⁻¹(4) = 1
When x = 4, the value of f⁻¹(x) is equal to 1
If you would like to solve 3 * x^2 + 24 * x = 27, you can do this using the following steps:
<span>3 * x^2 + 24 * x = 27
</span><span>3 * x^2 + 24 * x - 27 = 0
</span>3 * (x^2 + 8 * x - 9) = 0
x^2 + 8 * x - 9<span> = 0
</span>(x + 9) * (x - 1) = 0
1. x = - 9
2. x = 1
None of the above results is correct. The correct result would be {-9, 1}.
