What is the axis of symmetry and vertex for the function f(x) = 3(x – 2)2 4?
Travka [436]

we know that

The equation of a vertical parabola in vertex form is equal to

y=a(x-h)^{2}+k

where

(h,k) is the vertex

if a > 0 -----> then the parabola open upward (the vertex is a minimum)

if a < 0 -----> then the parabola open downward (the vertex is a maximum)

The axis of symmetry is equal to

x=h

In this problem let's analyze two cases

First case

f(x)=3(x-2)^{2}+4

the vertex is the point (2,4)

a=3

so

3 > 0 -----> then the parabola open upward (the vertex is a minimum)

The axis of symmetry is equal to

x=2

Second case

f(x)=3(x-2)^{2}-4

the vertex is the point (2,-4)

a=3

so

3 > 0 -----> then the parabola open upward (the vertex is a minimum)

The axis of symmetry is equal to

x=2

What is the answer of solve the following equations and verify your answer ​ ​
Thepotemich [5.8K]

<u>Explanation</u><u> </u><u>:</u>

<h3 />

<u>By doing cross multiplication, we get-----</u>

=>p-6=3(p+7)

=>p-6=3p+21 =>p-3p=21+6

=>-2p=27

=>p=27/-2

=>p=-27/2

<h3><u>Verification:</u></h3>

<u>By,putting the value of p in the equation, we get----</u>

<u>(</u><u>LHS)</u>=(-27/2+7)/(-27/2-6)=1/3<u>(</u><u>RHS)</u>

=>(-27+14/2)/(-27-12/2)=1/3

=>(-13/2)/(-39/2)=1/3

=>-13/2×2/-39=1/3

=>1/3=1/3

<u>Hence,LHS=RHS verified.</u>
