If you shift function f(x) a units right you'll get f(x-a) function.
So if you have f(x) = x², you'll get f(x-10) = (x-10)² - answer B
other formulas:
a units left: f(x+a)
a units up: f(x)+a
a units down: f(x)-a
Option C is correct.
try multiplying it out yourself. It should work

6x + 20
Step-by-step explanation:
- <u>To</u><u> </u><u>find</u><u> </u><u>:</u><u>-</u>
Perimeter of rectangle
- <u>Given</u><u> </u><u>:</u><u>-</u>
Length = 2x + 7
Breadth/width = x + 3
- <u>Solution</u><u> </u><u>:</u><u>-</u>
<em>We</em><em> </em><em>know</em><em> </em><em>that</em>
<em>
</em>
<em>Now</em><em> </em><em>we</em><em> </em><em>will</em><em> </em><em>substitute</em><em> </em><em>the</em><em> </em><em>values</em><em> </em><em>of</em><em> </em><em>length</em><em> </em><em>and</em><em> </em><em>breadth</em>
<em>
</em>
So if all same you just simplify The top : 2x+1+x+4 2x+x+1+4
3x+5 The bottom all same just use one .x-3 3x+5/x-3
