How do you find the f(x) inverse using fractions?

1 answer:

4 0

For example.. 1) switch places of x and y. x=3y+1 x=3 y +1
2) try to solve for y. so multiply the denominator by x to get rid of it
3) after multiplying, ur left with xy+x=3 x y + x=3
4) that converts to 2xy= x y =3
5) get rid of 2x on left by placing it on the right
6) convert y to inverse function

Which statement best describes the equation (x + 5)2 + 4(x + 5) + 12 = 0?

lidiya [134]

Answer:

Option 1 is correct.

Step-by-step explanation:

Given the equation $(x + 5)^2 + 4(x + 5) + 12 = 0$

we have to choose the best statement describes the above equation.

$(x + 5)^2 + 4(x + 5) + 12 = 0$ → (1)

As, the highest degree of its monomials i.e individual terms with non-zero coefficients is 2.

⇒ Degree of above equation is 2.

hence, the given equation is quadratic equation.

The general form of quadratic equation is

$ax^2+bx+c$

In variable u: $u^2+u+c=0$ → (2)

Now, compare equation (1) with (2), we say that

The equation is quadratic in form because it can be rewritten as a quadratic equation with u substitution u = (x + 5).

Option 1 is correct.
