Question

For the function f(x)=7x-(36)/(x), solve f(x)=4.

Answer 1

To solve the function f(x) = 7x - (36/x) for f(x) = 4, set the equation equal to 4 and solve the resulting quadratic equation for x.

Step-by-step explanation:

To solve the function f(x) = 7x - (36/x) for f(x) = 4, we set the equation equal to 4 and solve for x:

7x - (36/x) = 4

Multiplying both sides by x to get rid of the fraction yields:

7x2 - 36 = 4x

Move all terms to one side to set the quadratic equation to zero:

7x2 - 4x - 36 = 0

Now solve this quadratic equation for x, which may require using the quadratic formula, factoring, or numerical methods depending on the discriminant.
