Three functions are given below: f(x), g(x), and h(x). Explain how to find the axis of symmetry for each function, and rank the

functions based on their axis of symmetry (from smallest to largest).
f(x) g(x) h(x)
f(x) = 3(x + 4)2 + 1 g(x) = 2x2 − 16x + 15 h(x). graph of 2 times the quantity of x minus 1 squared, minus 3

The axis of symmetry is the number inside the parenthesis with the x, which is also the x value of the vertex.  And the +1 in f(x) is the y value of the vertex. But the x value has a sign opposite the sign inside the parenthesis with it because of the general form of the equation which is (x-h). So the vertex of f(x) has coordinates of (-4,1) and the axis of symmetry is x= -4.  For g(x), the coordinates of the vertex are found by completing the square. Putting it into vertex form gives you an equation of 2(x-4)^2 - 1 = y with a vertex of (4, -1) so the axis of symmetry is the line x = 4. The last one, h(x), is 2(x - 1)^2 - 3 = y and the vertex has coordinates of (1, -3) and the axis of symmetry is the line x = 1. Putting them in order you have f(x) as the least, h(x) as second, and g(x) as the greatest. If you can't complete the square on a quadrilateral or "read" the vertex form of a quadrilateral, you'll struggle with this.

A new company president is said to have caused the company "to do a 180." Before the new president, the company was losing $10,0
Anna71 [15]

The company most likely doing under the new president would be earning 10,000 per month.

<h3>How to find the correct statement?</h3>

A new company president is said to have caused the company "to do a 180."

Before the new president, the company was losing $10,000 per month.

Since a "180" usually refers to an opposite, also the opposite of "losing 10,000 per month" would happen but it's not.

So, the company would be earning money is most likely doing under the new president instead of losing money.

Answer:  one Apple costs £ 0.20, and one banana costs £ 0.60

Step-by-step explanation:

let x = the amount of apples

let y = the amount of bananas

4x + y = 1.40

7x + y = 2

this is à system of equations

simplify the top equation to   y = 1.4 - 4x

now plug that into the second equation and solve

7x + 1.4 - 4x = 2

3x + 1.4 = 2

3x = 0.6

x = 0.2

that means that one Apple costs £ 0.20

plug that back into the top equation

4x + y = 1.4

4(0.2) + y = 1.4

0.8 + y = 1.4

y = 0.6

so one banana costs £ 0.60

A student said that the y-intercept of the function y = 3 · 4x is 4. What is their mistake? What is the actual y-intercept?
patriot [66]

Answer:

<h2>The y intercept is 0</h2>

Step-by-step explanation:

the equation of a line is given as

y= mx+c

where

m= is the slope

c= is the y intercept

their mistake is that they did not recall that if the "c" is not shown, it is assumed to be zero (0)
