F(x)=x^2 what is g(x)?

Mathematics
1 answer:
Umnica [9.8K]3 years ago
8 0

Answer:

B

Step-by-step explanation:

You are given that a valid point on g(x) is (4,1) or y=1 when x=4

Substitute this point into each of the choices and see which one is valid.

A : g(x) = \frac{1}{4}x² = (1/4) (4²) = 4 ≠ 1 (not valid)

B: g(x) = [(1/4) x]² = [(1/4) 4]² = 1² = 1 (valid)

C: g(x) = 4x² = 4 (4²) = 64 ≠ 1 (not valid)

D: if you expand it out, you'll find that this is identical to option A which we determined earlier to be not valid.

Hence the only valid choice is B

What is the measure of y? 3 27 y Z * A y = [?] Give your answer in simplest form.​
Andrews [41]

Applying the geometric theorem, the measure of y = 9.

<h3>What is the Geometric Theorem?</h3>

The geometric theorem states that, h = √(ab), where h is the altitude of a right triangle, a nd b are the segments formed when the altitude divides the hypotenuse of a right triangle.

Thus:

y = altitude = ?

a = 3

b = 27

Substitute

y = √(3 × 27)

y = √81

y = 9

Therefore, applying the geometric theorem, the measure of y = 9.

Two lines, C and D, are represented by the equations given below:
hammer [34]
Given:
line C: y = x + 14
line D: y = 3x + 2

(6,20) or (3,11)

line C: y = 6 + 14 = 20  or y = 3 + 14 = 17
line D: y = 3(6) + 2 = 18 + 2 = 20   or  y = 3(3) + 2 = 9 + 2 = 11

(6,20), because both lines pass through this point.

PLEASE HELP. !!!!!!!!!

<h3>Answer:    (x+7)^2 + (y+2)^2 = 4</h3>

===========================================================

Explanation:

The center is at (h,k) = (-7,-2)

h = -7

k = -2

The radius is r = 2 units

Plug these three pieces of info into the template below and simplify

(x-h)^2 + (y-k)^2 = r^2

(x-(-7))^2 + (y-(-2))^2 = (2)^2

(x+7)^2 + (y+2)^2 = 4

You can use a tool like Desmos or GeoGebra to confirm the answer.
