Answer:
see the explanation
Step-by-step explanation:
we have
we know that
To cross multiply, start by multiplying the numerator of the left-hand fraction by the denominator of the right-hand fraction.
2(8)
Then, multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction.
7(28)
Next, set the 2 products equal to each other.
2(8)=7(28)
Answer:
a = 1
Step-by-step explanation:
(x²+x-1)(x-1) = x³+x²-x-x²-x+1 = x³-2x+1
Answer:
It's odd.
Explanation:
A function is odd when <span><span>f<span>(−x)</span></span>=−<span>f<span>(x)</span></span></span>
<span><span>f<span>(−x)</span></span>=6<span><span>(−x)</span>3</span>−2<span>(−x)</span></span>
<span>=−6<span>x3</span>+2x</span>
<span>=−<span>(6<span>x3</span>−2x)</span></span>
<span>=−<span>f<span>(x)</span></span></span>
Thus, the function is odd.
If a function is odd, then it is symmetric over the x-axis.
