Do you want help interpreting or using "f(4) = 75", or did you mean something else (like f'(4) = 75)? A few quick notes depending on what you mean:
- If f(4) = 75, that just means the point (4, 75) lies on the graph of f.
- If you need the y-intercept for a linear function with known slope m: f(x) = m x + b, then 75 = 4m + b so b = 75 − 4m.
- If you want the inverse value, f⁻¹(75) = 4.
- If you meant the derivative f'(4) = 75, that gives the slope of the tangent to f at x = 4.
- If you have a formula with an unknown parameter (for example f(x) = ax^2 + bx + c) and are told f(4) = 75, plug x = 4 and solve: a(4)^2 + b(4) + c = 75.
Tell me what you want to do (find a function, solve for a parameter, graph, check a derivative, etc.) and any additional info/equations, and I’ll continue.
