Answer:
<em>option: C </em>is correct.
Step-by-step explanation:
since, we are given a parent function f(x) as: f(x)=x.
We are asked to find what change will occur in the function when the parent function f(x) is replaced by f(9x).
let g(x) be the function formed by replacing f(x) with f(9x) i.e.
g(x)=f(9x)=9x.
clearly the slope of the function g(x)=f(9x) is 9. ( since on comparing the equation with the slope intercept form <em>y=mx+c</em>; where <em>m</em> is the<em> slope</em> of the line and <em>c</em> is the <em>y- intercept</em><em>)</em>.
whereas the slope of the function f(x)=x is 1.
<em>Hence there is an increment of slope by a factor of 9.</em>
<em>Hence, option C is correct.</em>
B) 4/9 is correct

Answer:
<h2>a) Histograma (histogram).</h2>
Step-by-step explanation:
First of all, a continuous variable only admits whole numbers, not decimals.
Now, in statitics, there are several way to reprepsent some data collected from a survey. The most popular tool are bar-graphs or histograms, they are used to show frequency distributions through graphs, where we use interval classes.
Therefore, the right answer is a.
Answer:multiplication Ex: 3 x 2 = 6
Division Ex: 6/2 =3
Step-by-step explanation:
3 x 2 = 3+3, add 3 2 times
6/2 = How many 2’s go into 6
