Describe the end behavior of the function f(x)=-2x^4- x^3 +3.

Hoochie [10]

Answer:

Step-by-step explanation:

For a polynomial , the behaviour as x gets large is determined by the term of greatest degree,

f(x) = - 2 $x^{4}$ - x³ + 3

Is of even degree with a negative leading coefficient , then

f(x) → - ∞ as x → + ∞ and f(x) → - ∞ as x → - ∞

1. The graph of every exponential function f(x)= ax, a>0, a≠1, passes through what three points(in terms of a)? Explain.

Anvisha [2.4K]

The exponential function
f(x) = a^x
can pass through all points as long as x is any real number

As an example, we can choose values of x.
x = -4, x = 0, x=100

The value of the function in terms of a would be
f(-4) = a^-4
f(0) = a^0 = 1
f(100) = a^100

What is the value of x?<br> Please show the steps

nordsb [41]

Let D be the endpoint of the angle bisector opposite A on lying on side BC. The angle bisector theorem states that the ratio of BD to CD is equal to the ratio of AB to AC. In this case, you have

$\dfrac{2x-1}{3x}=\dfrac9{15}$

(This is the same equation that you have, it's just rearranged.)

Multiply both sides by $3x$ and 15.

$15\times3x\times\dfrac{2x-1}{3x}=15\times3x\times\dfrac9{15}$
$15(2x-1)=3x\times9$

Now you can solve for $x$ .

$30x-15=27x$
$3x=15$
$x=5$
