Given the function y=3x4 -8x3 + 4x2 - x -5 what is the end behavior?

1 answer:

3 0

y=3x4 -8x3 + 4x2 - x -5 is an even function. Highest power is x^4 (not x4).

As x increases in the + direction or decreases in the - direction, 3x^4 will increase in Q I and Q II respectively. Not a parabola, but looks like one, opening up.

Solve for the following equation step by step and justify your steps when using an exponential property.

mel-nik [20]

x = $\frac{5}{7}$

using the ' laws of exponents '

• $a^{m}$ × $a^{n}$ = $a^{( m + n )}$

• $a^{m}$ ÷ $a^{n}$ = $a^{(m - n)}$

• ( $a^{m}$ )^n = $a^{mn}$

$7^{2}$ × $7^{3}$ = $7^{5}$ ÷ $7^{3x}$ = $7^{5 - 3x}$

$7^{4x}$ = $7^{5 - 3x}$

equating the exponents since bases on both sides are 7

4x = 5 - 3x

7x = 5 ⇒ x = $\frac{5}{7}$
