The functions x) and g(x) are shown on the graph.f(x) = x2What is g(x)?​

Mathematics
1 answer:
Nadya [2.5K]3 years ago
6 0

Answer:

C. g(x) = 4x²  

Step-by-step explanation:

The general equation for a parabola is  

y = ax² + bx +c  

Since ƒ(x) = x², a=1, b =0, c =0

For g(x), the vertex is still at  the origin, so

g(x) = ax²

The graph passes through (1,4).

Insert the coordinates of the point.

4 = a(1)²

a = 4

g(x) = 4x²

The figure below shows that the graph of g(x) = 4x² passes through the point (1, 4).

Hey factory could produce 84 toy robots in one day. The purchasing equipment. Now they can produce 105 robots in one day. What i
Finger [1]

Answer:

The answer to the question is

25 % increase in production rate

Step-by-step explanation:

To solve the question, we note that

Initial number of products = 84 toy robots per day

Present production rate = 105 robots per day

The percentage increase is given by the increase in production rate divided by the original production rate multiplied by 100

Where increase in production rate = 105 - 84 = 21

Percentage increase = 21/84 ×100 = 25 % increase

What is the domain of the function on the graph?
hammer [34]

Answer:

Option (4)

Step-by-step explanation:

Domain:

Domain of function is defined by the x-values (Input values) on the graph.

Range:

Range of a function is defined by the y-values (output values) on the graph.

From the graph attached,

x-values are starting from (-3) to infinity.

Therefore, domain of the function will be all real numbers greater than equal to (-3).

Option (4) will be the answer.

Julian is 10 years younger than Thomas. The sum of their age is 40. What is Thomas age
Karolina [17]

So first we subtract 10 from 40 and get 30. We divide this by the number of people (2) to get Julian's age: 15. We add 10 to this to get Thomas age = 25. 25 + 15 = 40

Thomas is 25 years old.
