Answer:

Step-by-step explanation:

You need to first put the numbers in suitable catagories

0-120

120-130

130-140

140-150

then figure out the frequency of them

0-120=4

121-130=20

131-140=2

141-150=2

then put in a graph(sry its not very good i was in a rush)

The function f(x)=(x-1)^2-4 is not one-to-one. If you restrict the domain for f(x) to x(less than or equal to symbol)1, what is

olasank [31]

$\text{We have been given the function }\\
f(x)=(x-1)^2-4\\
\text{Let f(x)=y}\\
y=(x-1)^2-4\\
\text{Swap x and y, we get}\\
\\
x=(y-1)^2-4\\
\text{Now we solve for y}\\
(y-1)^2=x+4\\
\\
y-1=\pm \sqrt{x+4}\\
\\
y=1\pm \sqrt{x+4}\\
\\
f^{-1}(x)=1\pm \sqrt{x+4}\\$
