Question

What are the x-intercepts of this quadratic function?
g(x) = -2(x - 4)(x + 1)

Answer 1

Answer:D (4,0) and (-1,0)

Explanation:

Answer 2

4 and -1

Explanation:

A quadratic function is given to us and we need to find the x Intercepts of the given function . The function is ,

`\bf \implies g(x) = -2( x -4)(x+1)`

Step 1 : Equate the function with 0,

`\bf \implies -2( x -4)(x+1) = 0`

Step 2: Equating with 0 :-

Now equate each factors seperately with 0 , to get the x Intercepts.

Step 3: Finding the intercepts :-

`\bf \implies x - 4 = 0 \\\\\implies\boxed{\bf\blue{ x = 4 }}`

Again ,

`\bf \implies x + 1 = 0 \\\\\implies\boxed{ \blue{\bf x = -1}}`

Hence the x intercepts are 4 and -1 .
