y = (x+2)(x-6)(x+7)

<span>(x+2)(x+7)
x^2 - 6x + 2x - 12
x^2 - 4x - 12</span>

<span /><span>(x^2 - 4x - 12)(x + 7)
x^3 + 7x^2 - 4x^2 - 28x - 12x - 84
x^3 + 3x^2 - 40x - 84</span>

<span /><span>y = x^3 + 3x^2 - 40x - 84
</span>

y = (x + 2) (x -6) (x + 7) \\ \\ i.e, y = (x+2) (x^2 - x - 42) \\\\ => y = x^3 + 3x^2 - 40x - 84

I only really need the domain and range, intervals, and end behavior. My Precalculus class never covered piecewise functions so
Serjik [45]

(a)

Domain:

we know that domain is all possible values of x for which any function ios defined

Here, curve is defined for all values of x

so, domain is

(-\infty,\infty)

Range:

Range is all possible values of y for which x is defined

minimum value of y is -4

maximium value of y is +inf

so, range is

[-4,\infty)

(b)

x-intercept:

It is the value of x where f(x)=0

so, the point where curve intersects on x-axis

and we get

2x^2-4=0

x=\sqrt{2}

and

x=-5

(c)

Increasing interval:

where curve is moving upward

we can see that

(0,\infty)

Decreasing interval:

where curve is moving downward

we get

(-\infty,-1)U(-1,0)

Constant:

constant means horizontal line

there is no horizontal line here

so, it does not exist

(D)

End behavior:

when x-->+inf

y is moving upward

so, y---->+inf

when x-->-inf

y is moving upward

so, y---->+inf

(E)

we can see that curve jupms at x=-1

so, there is discontinuity at x=-1

and this is jump type of discontinuity

(F)

For odd:

f(-x)=-f(x)

For even:

f(-x)=f(x)

we can see that none of them holds true

so, this is neither

2(4x+1) - 5x + 2 = 3x + 4 Help Please :)
Gelneren [198K]

Answer: All real numbers are solutions

Step-by-step explanation:

first lets distributive the 2(4x+1) to get 8x+2 because 2*4x= 8x and 2*1= 2

now the equation is 8x+2-5x+2= 3x+4

(COMBINE LIKE TERMS)

8x-5x=3x

2+2= 4

now the equation is 3x+4= 3x+4 (this means all real nubers are solutions)
