Inverse of a function is also a function, if and only if the function is One - to - One. This means no y value occurs in the range of the function more than once.

If we observe the given options, we can see option B, C and D have some repeated values of y. Only the function in option A is one to one. Hence the inverse of function given in option A will also be a function.

So, the answer to this question is option A

True or False? Def is a right triangle.

myrzilka [38]

Answer:

Step-by-step explanation:

We can determine if the triangle is a right triangle by using the Pythagorean theorem

a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse

25^2 + 27^2 = 48^2

625+729=2304

1354 ≠2304

This is not true, so this is not a right triangle

Answer:

C

Step-by-step explanation:

Given that Q varies inversely as the square of p then the equation relating them is

Q = $\frac{k}{p^2}$ ← k is the constant of variation

To find k use the condition Q = 36 when p = 7

k = Qp² = 36 × 7² = 36 × 49 = 1764

Q = $\frac{1764}{p^2}$ ← equation of variation

When p = 6, then

Q = $\frac{1764}{6^2}$ = $\frac{1764}{36}$ = 49 → C
