The graph of the function f is shown. The domain of f is [0,50]. What is the range of g(x)=4f(x)?

sergij07 [2.7K]

Answer:

The range of $g(x)$ is $[0,7]$ .

Step-by-step explanation:

We must remember that range of function $f(x)$ corresponds to the set of values of $y$ in the graph (+y direction). Given that $g(x)$ is a stretched version of $f(x)$ , the range of $g(x)$ corresponds to the range of $f(x)$ multiplied by 4. Then,

$Ran\{g(x)\} = 4\cdot Ran\{f(x)\}$

$Ran\{g(x)\} = 4\cdot [0,1.75]$

$Ran\{g(x)\} = [0, 7]$

The range of $g(x)$ is $[0,7]$ .

P 140 units

A 1200 units^2

Step-by-step explanation:

The length of the rectangle is 20 to -20 = 20 - -20 = 40 units

The width of the rectangle is 20 to -10 = 20 - -10 = 30 units

The perimeter is given by

P = 2 ( l+w) = 2 (40+30) = 2 (70) = 140 units

The area is given by

A = lw = 40*30 = 1200 units^2
