Question

Assume a mathematical function is defined by y = f(x) = 2x - 10. At what value
of x will f(x) intersect the X-axis​

Answer 1

Answer:

at x=5 because at that point y will be zero

Answer 2

Answer:

At x = 5, the mathematical function  y = 2x-10 will intersect the x - axis.

Step-by-step explanation:

Given, Mathematical Function y = f(x)= 2x-10

At x axis, the value of f(x) = 0. So, for the function to intersect with x - axis the value of y must be equal to zero.

So, y =  f(x) = 2x-10 = 0

            = 2x = 10

           =  x = 10/2 = 5

Therefore, at x = 5, the mathematical function y = f(x) = 2x-10 will intersect the x - axis.
