Finding the Equation of a Tangent Line Perpendicular to a Given Line

Click For Summary
SUMMARY

The discussion focuses on finding the equation of a tangent line to the function f(x) = x² - 4x + 1 that is perpendicular to the line represented by x + 2y = 10. The slope of the given line is -1/2, leading to a tangent slope of 2. By calculating the derivative, f'(x) = 2x - 4, the user determines the point where the slope equals 2 to find the tangent line's equation. The user successfully concludes their solution without needing further assistance.

Homework Statement



Find the equation of the tangent line on the function, f(x) = X^{2}-4x+1, which is perpendicular to the line, x+2y=10.

Homework Equations



The Attempt at a Solution



x+2y=10
2y = 10-x
y=-1/2x+5
Slope of perpendicular is -1/2, so slope of tangent is 2.
The derivative of f(x):
f'(x)= 2x-4.
f'(x) represents the slope of the tangent = 2
Where can I go from here?
