Answer:

  Equation of function,   y = (x-1)²

Step-by-step explanation:

The general formula of a parabola symmetric about x - axis is given by (x-h)²=4a(y-k), where (h,k) is the vertex.

Here (h, k) = (1,0)

So, we have (x-1)²=4a(y-0)

                    (x-1)²=4ay

One point on the parabola is (0,1) since y intercept is 1.

Substituting

         (0-1)²=4 x a x 1

           1 = 4 a

           a=\frac{1}{4}

Equation of parabola,

    (x-1)^2=4*\frac{1}{4} *y\\ \\ (x-1)^2=y\\ \\ y=(x-1)^2

Equation of function,   y = (x-1)²

If f(x)=x^2 and g(x)=1÷2x+3 find g(f(-1))
gogolik [260]

ANSWER

g(f( - 1)) = \frac{1}{5 }

EXPLANATION

The given function is:

f(x) =  {x}^{2}

and

g(x) =  \frac{1}{2x + 3}

g(f(x)) = g( {x}^{2} )

g(f(x)) = \frac{1}{2{x}^{2} + 3 }

To find g(f(-1)), we substitute x=-1, to obtain;

g(f( - 1)) = \frac{1}{2{( - 1)}^{2} + 3 }

We simplify the square in the denominator to get,

g(f( - 1)) = \frac{1}{2+ 3 }

We now add the denominator to obtain;

g(f( - 1)) = \frac{1}{5 }
