T is a point in the line segment SU

SU = ST + TU

SU = 4x

ST = 2x + 6

TU = 4

[tex]4x =( 2x + 6 )+ 4 \\ 4x = 2x + 10 \\ 4x - 2x = 10 \\ 2x = 10 \\ x = \frac{10}{2} \\ \\ x = 5[/tex]

x = 5

ST = 2x + 6 = (5×2) + 6

ST = 16

What are the domain and range of g(x) = -1/4 (x-17)^2 + 61?


​

Answers

Answer:

Step-by-step explanation:

It can not be bigger then 61

The domain and range of g(x) = -1/4 (x-17)^2 + 61 is g(x) ≤ 61 and the domain is that it is all real numbers.

Calculation of the domain and range:

Since the function is g(x) = -1/4 (x-17)^2 + 61

It defined that it is the polynomial and also the whole real number

So based on this, we can say that The domain and range of g(x) = -1/4 (x-17)^2 + 61 is g(x) ≤ 61 and the domain is that it is all real numbers.

hence, the first option is correct.
