Given the trinomial 3x2 − 6x + 5, what is the value of the discriminant?

yan [13]

$\bf \begin{array}{llcccll}
& 3 x^2& -6 x& +5\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}
\\\\\\
discriminant\implies b^2-4ac\implies (-6)^2-4(3)(5)$

What is the multiplicative rate of change of the exponential function shown on the graph? 1 4

marta [7]

The answer:
the main formula for computing the multiplicative rate of change is given by:

Mutiplicative Rate of Change = [f(x2)/f(x1)] / (x2 -x1)
this formula can be written as
[f(x2)/f(x1)] / (x2 -x1) = [f(x2) * (x2 -x1) /f(x1)]

for example we can take (x1, f(x1))= (0, 2) and (x2, f(x2))= (1, 5)
therefore,
Mutiplicative Rate of Change = [5/2] / (1-0)= 5/2= 2.5

the answer is 2.5
