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

Z + 6 over 3 = 2z over 4
Black_prince [1.1K]
    \frac{z + 6}{3} = \frac{2z}{4}   Multiply both sides by 3
    z + 6 = \frac{(3)2z}{4}   Multiply both sides by 4
(4)z + 6 = (3)2z   Simplify
4z + 24 = 6z   Subtract 4z from both sides
        24 = 2z   Divide both sides by 2
         12 = z     Flip the sides to make it easier to read
          z = 12
