X2 + y2 = 4 determine if the relation is a function

Mathematics
1 answer:
Mama L [17]3 years ago
4 0

Answer:

It is not a function.

Step-by-step explanation:

x^2 + y^2 = 4.

Let x = 1:

(1)^2 + y^2 = 4

y^2 = 4 - 1 = 3

So y = √3, -√3.

So we see that for one value of x we get 2 values of y.

So the relation is a one-to-many relation which is not a function.

Functions are either one-to-one or many to-one.

B) 196 cubic cm or something like that... First you multiply 7x5x14=490... then you divide 490/5 because you're working in fifths and get 98... the white is only two-fifths so you multiply 98 times 2 and get 196

Finding angle measures using triangles
S_A_V [24]
Because HI and JK are parallel, that makes their angles congruent. So angle K equals angle I
So the interior angles of a triangle add up to 180°
So, Angle I + angle H + angle x =180°
60°+56°+x°=180°
116°+x°=180°
X=180-116
X=64°

Rewrite the function f(x)=-2(x+2)^2+6 in the form f(x)=ax^2+bx+c
Romashka [77]

Answer:

f(x) = -2x² - 8x - 2

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Expand by FOIL (First Outside Inside Last)
  • Standard Form: f(x) = ax² + bx + c
  • Vertex Form: f(x) = a(bx + c)² + d

Step-by-step explanation:

<u>Step 1: Define function</u>

Vertex Form: f(x) = -2(x + 2)² + 6

<u>Step 2: Find Standard Form</u>

  1. Expand by FOILing:                         f(x) = -2(x² + 4x + 4) + 6
  2. Distribute -2:                                     f(x) = -2x² - 8x - 8 + 6
  3. Combine like terms (constants):     f(x) = -2x² - 8x - 2
