Laura & Mary are doing their homework together.

Mathematics
1 answer:
True [87]3 years ago
8 0
Laura is correct.

A function is a relation in which every x-value corresponds with no more than one y-value.  In this problem, the x-value 1 has two different answers; this means it is not a function.

Additionally, if you graphed this, it would not pass the vertical line test.

I really need help with this
Alex Ar [27]

Answer:

A. x = 3, y = -3

B. a = -2, b = 5

C. try your best ill see u later

Step-by-step explanation:

Okay I'mma state some stuff first 3^a + 3^b = 3^(a+b)

and 3^a/3^b = 3^(a-b)

So first equation 3^3*3^-3=3^0

So second equation 3^3/3^-2 = 3^5

So third equation I dont really know the rule but I'mm just plug in a random number for g, like 2, then solve the thing like a normal equation.

So 3^-3 x f^-3 = 12^2 = 144, f^-3 = 144/(3^-3 or 1/27) = 144 x 27 = 3888

so f^-3 = 3888, f = well its an imaginary number according to calculator so u try your best on the last one
