Answer:
x ∈ {-0.465, 1.014}
Step-by-step explanation:
The equation can be cast in the form f(x) = 0, and solved easily using a graphing calculator. That shows x ≈ -0.465 and x ≈ 1.014. The same calculator can iterate the roots to full calculator precision.
__
The equation can be made a quadratic by the substitution ...
z = e^(2x)
Then we have ...
Step-by-step explanation:
3x+x=-7-5
4x=-12
x=-12/4
x=-3
The only grab function is 2 because 1 and 3 don’t even make sense it’s not a negative slope, positive slope, undefined slope, or zero slope therefore it’s nothing.
Step-by-step explanation:
al nth term:
numerator:
denominator:
so nth term :
b). 1; 11; 27; 49
first difference: 10; 16; 22
second difference :6
formula for 1st difference:3a+b
formula for 2nd difference:2a
Therefore:
2a=6
a=3
3a+b=10
sub in a
3(3)+b=10
9+b=10
b=1
sub into quadratic formula
So Tn:
