Which graph shows a function whose inverse is also a function?
Answers
Step-by-step explanation:
Using the concept of inverse function, it is found that the first graph shows a function whose inverse is also a function.
----------------------------------------
A function f(x) will only have an inverse function if: f(a) = f(b) \leftrightarrow a = bf(a)=f(b)↔a=b , that is, a value of y will have only one respective value of x.
----------------------------------------
In the first graph, for each value of y, there is only one value of x, so the inverse is also a function, and this is the correct option.
In the second graph, for example, y = 0 when x = -1 and when x = 1, so the inverse is not a function.
In the third graph, for example, y = -3 when x = 0 and x = 2, so the inverse is not a function.
In the fourth graph, for example, y = 1 for two values of x, so the inverse is not a function.

50% of 320 is equal to 80% of what number?
Answers
Answer:
50% of 320 is equal to 80% of 200
Step-by-step explanation:
[tex]\sf{50\% \times 320}[/tex]
[tex]\sf{ = \frac{50}{100} \times 320 }[/tex]
[tex]\sf{ = \frac{16000}{100} }[/tex]
[tex] = \sf{160}[/tex]
-
[tex]\sf{160 \div 80\%}[/tex]
[tex]\sf{ = 160 \div \frac{80}{100} }[/tex]
[tex]\sf{ =\cancel{ 160} \times \frac{100}{\cancel{80}} }[/tex]
[tex]\sf{ = 2 \times 100}[/tex]
[tex] = \boxed{\sf{\underline{\purple{200}}}}[/tex]
Answer:
50% of 320 is equal to 80% of 200.
Step-by-step explanation:
Given,
50% of 320 is equal to 80% of a number (let it be x)
Now,
50% of 320
= 50% × 320
= 50/100 × 320
= 50/10 × 32
= 5 × 32
= 160
Also now,
160 is equal to 80% of x.
80% of x = 160
80% × x = 160
80/100 × x = 160
8/10 × x = 160
4/5 × x = 160
4/5x = 160
x = 160 ÷ 4/5
x = 160 × 5/4
x = 40 × 5
x = 200
