How do I find 2 unknown variables of f(x) when given the tangent line to a function at a point?
Find a and b if the tangent line to the function #f(x)=x^4# +a#x^2# +b at x=1 is y=2x+3
How do I find a and b in this equation?
Find a and b if the tangent line to the function
How do I find a and b in this equation?
1 Answer
Take the derivative of
Explanation:
So we know by the definition of tangent that the tangent line should be equal to the function at
If the equation for the tangent line is
Now that we know
