What is the equation for g, which is f(x) = 2x2 + 3x − 1 reflected across the y-axis? Group of answer choices g(x) = −2x2 − 3x −
Sergio [31]

Answer:

g(x) = 2x^2 - 3x - 1

Step-by-step explanation:

Given

f(x) = 2x^2 + 3x - 1

Required

Determine g(x), if f(x) is reflected across the y axis

<em>When a function (x,y) is reflected across the y axis, the new function becomes (−x,y).</em>

<em />

In other words,

g(x) =  f(-x)

Calculating f(-x)

f(-x) = 2(-x)^2 + 3(-x) - 1

f(-x) = 2x^2 - 3x - 1

Substitute g(x) for f(-x)

g(x) = 2x^2 - 3x - 1

<em>Hence;</em>

g(x) = 2x^2 - 3x - 1

Say if the Earth rotates 1.25 degrees in 5 mintues. But a classmate wants to find out how many degrees the Earth can rotate in 2
givi [52]

Her error was dividing them by 2 she would place 1.25 over 5 then divide by 5 to get the unit rate per minute then multiply the quotient by 2 to get the rate of degrees moved for 2 minutes which is .5  or .50 degrees every two minutes.

The equation of a circle is given below. Identify the center and radius. Then graph the circle.
Blizzard [7]

Answer:

  • Center = (3, 0)
  • Radius = 3
  • Graph = see below

Concept:

Here, we need to know the idea of the circle equation.

Circle equation: (x - h)² + (y - k)² = r²

(h, k) = center

r = radius

x = variable

y = variable

Solve:

<u>Given expression </u>

(x - 3)² + y² = 9

<u>Find the point of the center</u>

(h, k) = \boxed{(3,0)}

<u>Find the length of the radius</u>

r² = 9

\boxed{r=3}

Hope this helps!! :)

The Quinn family drove 228 miles in 4 hours at a constant rate. Which equation can be used to determine how far they traveled ea
anyanavicka [17]
What can be used on this is the distance over time formula, so what you,do is divide 228 by 4 to get the distance traveled in one hour. And 288/4=57. So they traveled 57 mi in one hour. Hope this helped.
