Answer:

minimum

Step-by-step explanation:

Given a quadratic in standard form : y = ax² + bx + c : a ≠ 0

Whether the function is maximum or minimum can be determined by consideration of the sign of the coefficient a

• If a > 0 then minimum

• If a < 0 then maximum

For y = - 4 + 3x² the value of a is 3 > 0

Hence y = - 4 + 3x² is a minimum

Mathematics help please!!!!!!!!!<br><br> what is -0.0833333333333 converted into a fraction?
VladimirAG [237]

Answer:

- 1/12

Step-by-step explanation:

Let -0.0833333 = x  ---  (1)

Multiply both sides by 10.

-0.833333 = 10x   --- (2)

Subtract (2) from (1),

0.75 = -9x

-9x = \frac{75}{100}

= \frac{3}{4}

x=-\frac{3}{36}

x=-\frac{1}{12}
