Which function is a quadratic function? u(x) = –x + 3x2 – 8 v(x) = 2x2 + 8x3 + 9x y(x) = x2 + 3x5 + 4 z(x) = 7x2 + 2x3 – 3

Answer:

u(x) = –x + 3x2 – 8

Step-by-step explanation:

The functions are;

u(x) = –x + 3x2 – 8

v(x) = 2x2 + 8x3 + 9x

y(x) = x2 + 3x5 + 4

z(x) = 7x2 + 2x3 – 3

A quadratic function is a function that has the form  f(x) = ax2 + bx + c where a, band c are numbers with a not equal to zero. The maximum degree must be 2.

Among all the options, the one that matches the form is;

u(x) = –x + 3x2 – 8

Answer:

V = 408    SA = 378

Step-by-step explanation:

To find the volume, you need to first find out the area and multiply it by overall length.

A = 1/2 (6)(8)

= 24

Volume = 24 x 17

= 408

Surface Area

SA = Front and Back + Right Side + Left Side + Bottom

= 2 [1/2 (6) (8)] + (17 x 10) + (3 x 8) + (17 x 8)

= 2 (24) + 170 + 24 + 136

= 48 + 170 + 24 + 136

= 378

Hey can you please help me posted picture of question
ICE Princess25 [194]
The answer is true.

Method 1:
The given function is a cubic function. And inverse of a cubic function is also a function.

Method 2:
Since the function is one-to-one function i.e it passes the horizontal line test, its function will pass the vertical line test which is a test if a relation is a function or not.

So, yes the inverse of G(x) will be a function.
