Answer:
<h2>There 2 x-intercepts can have for a quadratic function.</h2>
Step-by-step explanation:
X-intercepts means, the value of y is 0.
For any function, x-intercepts mean the set of values of x, for which y = 0.
A quadratic function means a polynomial of degree 2.
The degree of any polynomial determines the number of x-intercepts of the polynomial.
Since, the quadratic function is a polynomial of degree 2, it has 2 x-intercepts.

Answer:
son = 10 , father = 40
Step-by-step explanation:
Let Five years ago the age of son be x years and age of father be 7x years
Present age of son =x+5
Present age of father =7x+5
5 years later their age will (x+10) and (7x+10)
∴7x+10=3(x+10)
7x−3x=20
4x=20
x=5
So, the present age of son=x+5=5+5=10years
and the present age of father=7x+5=35+5=40years
hope it helps you
