F(x)=2x^2+3 & g(x)=x^2-7 find (f-g)(x)
kicyunya [14]

Answer:

\boxed{\sf (f - g)(x) = x^2 + 10}

Given:

f(x) = 2x² + 3

g(x) = x² - 7

To Find:

(f - g)(x)

Step-by-step explanation:

(f -g)(x) = f(x) - g(x)

= (2x² + 3) - (x² - 7)

= 2x² + 3 - x² + 7

= 2x² - x² + 3 + 7

= x² + 3 + 7

= x² + 10

Which function in vertex form is equivalent to f(x) = x2 + x +1? f(x) = (x + one-quarter) squared + three-quarters f(x) = (x + o
a_sh-v [17]

The function in vertex form is f(x)=(x+\frac{1}{2})^{2}+\frac{3}{4} ⇒ 3rd answer

Step-by-step explanation:

The vertex form of the quadratic function f(x) = ax² + bx + c is

f(x) = a(x - h)² + k, where

  • a is the coefficient of x²
  • (h , k) are the coordinates of the vertex point
  • h=\frac{-b}{2a} , wher b is the coefficient of x
  • k = f(h), that means value f(x) when x = h

∵ f(x) = x² + x + 1

∴ a = 1 , b = 1

∵ h=\frac{-b}{2a}

- Substitute the values of a and b to find h

∴ h=\frac{-1}{2(1)}

∴ h=\frac{-1}{2}

Substitute the value of x in f(x) by the value of h to find k

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

∴ f( \frac{-1}{2} ) = \frac{1}{4}-\frac{1}{2}+1

∴ f( \frac{-1}{2} ) = \frac{3}{4}

- k is the value of f(x) when x = h

∵ h = \frac{-1}{2}

∴ k = f( \frac{-1}{2} )

∴ k = \frac{3}{4}

Substitute the values of a, h and k in the vertex form

∵ f(x) = a(x - h)² + k

∵ a = 1 , h=\frac{-1}{2} , k=\frac{3}{4}

∴ f(x)=1(x-\frac{-1}{2})^{2}+\frac{3}{4}

∴ f(x)=(x+\frac{1}{2})^{2}+\frac{3}{4}

The function in vertex form is f(x)=(x+\frac{1}{2})^{2}+\frac{3}{4}
