What is the vertex of the parabola given by the equation y = x2 + 4?

The vertex of the parabola is (0,4), because you can use -b/2a to find the x coordinate a of the vertex. There is no b so b=0 and 0/anything is 0. Then you can plug 0 into the equation to find the y coordinate of the vertex. When you plug in 0 you get 4, so the vertex is (0,4)

Suppose you Just purchased a used truck. The number of miles on the odometer can be represented by the equation y = x + 40, 000,
igor_vitrenko [27]

Answer: f(x)= x+40000

Step-by-step explanation:

We write a function f(x) which gives the values of the function that are dependent on the independent variable "x".

Given: The number of miles on the odometer can be represented by the equation y = x + 40, 000, where y is the number of miles on the odometer, and x is the number of miles you have driven it.

Here y is dependent on x, so we replace y by f(x), then we get

f(x)= x+40000   which is the required answer.
