Step-by-step explanation:
The answer would be $713.23
If you would like to find the number which belongs in the blank to complete the square, you can calculate this using the following steps:
f(x) = 5(x^2 - 4x + a) + 15
a ... the number = ?
<span>x^2 - 4x + a = (x - 2)^2 = x^2 - 4x + 4
</span>a = 4
The correct result would be 4.
Given:
The function is

To find:
The domain, range, and intercepts of the function.
Solution:
We have,

It is a linear function, and domain and range of these types of functions are all real numbers.


Put x=0 in f(x), to find the y-intercept.



So, the y-intercept is 11.
Put f(x)=0 in f(x), to find the x-intercept.



Divide both sides by 7.

So, the x-intercept is
.
Therefore,
.
