How the quadratic formula works:
For any quadratic equation ax² + bx + c = 0, the solution is
.
In the case of our equation 7x² - x = 7, first we need to subtract 7 from each side so that we have 0 on the right.
7x² - x - 7 = 0
Identify the values of a, b, and c.
a = 7, b = -1, and c = -7.
Plug these into our quadratic formula and solve.
There are two values for x: (1+√197)/14 and (1-√197)/14.
The approximate values for these are 1.073976 and -0.931119.

Answer:
B
Step-by-step explanation:
So we have the function:
To find the inverse, flip f(x) and x, change f(x) to f⁻¹(x), and solve for it. Thus:
Subtract 32 from both sides:
Multiply both sides by 5/9. The right side will cancel. Thus:
Our answer is B.
And we're done!
