Answer:
C
Step-by-step explanation:
Quadratic model is shaped like a "U", or a parabola
Quartic model is shaped like a "W", highest degree is 4 (x^4).
Linear model is a line.
Cubic model is x^3, shaped like a curvy snake.
Looking at the graph, it <em>clearly</em> shows a line. So, linear model is the answer.
C is the correct answer.
The correct question is
Which is the best approximation to a solution of the equation
e^(2x) = 2e^{x) + 3?
we have that
e^(2x) = 2e^{x) + 3-----------> e^(2x)- 2e^{x) - 3=0
the term
e^(2x)- 2e^{x)----------> (e^x)²-2e^(x)*(1)+1²-1²------> (e^x-1)²-1
then
e^(2x)- 2e^{x) - 3=0--------> (e^x-1)²-1-3=0------> (e^x-1)²=4
(e^x-1)=2--------> e^x=3
x*ln(e)=ln(3)---------> x=ln(3)
ln(3)=1.10
hence
x=1.10
the answer is x=1.10

Answer:
Step-by-step explanation:
if you use a graphing calculator you we see that the smaller the leading coeffient the wider the parabola.
or use a table and plug in values for y for each x
y = x² 5x² 15x²
x = 1 1 5 15
x = 2 4 20 60
y is larger for a larger ax² a coeffient
so the is more narrow for a higher coeffient
f(x) = 5x² has the smallest coeffient so the widest parabola
3/4 im pretty sure just do 3 divided by 4 to tell
