In the xy -plane, the graph of the function f(x)=   has two x -intercepts. What is the distance between the x-intercepts?

The correct answer is: 3

Explanation:

• We have given a quadratic expression  .
• We have to find the distance between the x- intercept .
• We will first find the points where it cut  x-axis and then find the distance between them

Step 1 of 1:

• We have a quadratic expression
  
• For finding the points where it cut x-axis , we have to do f(x)=0
  

So,




Therefore,
x = - 1
x = - 4
Now the distance between them will be



3
Hence, Option C is correct.
