Answer:
can you elaborate more on your question please
if this is the question or similar. An exponential function is given in the form f(x)-a*bx. If f(0)=3 and f(1)=15, what's the value of f(-2)?
this is how to solve it:
f(0) = 3 = a*b0 Therefore 3 = a (1)
f(0) = 3 = a*b0 Therefore 3 = a (1) f(1) = ab = 15
f(0) = 3 = a*b0 Therefore 3 = a (1) f(1) = ab = 15 3b =15
f(0) = 3 = a*b0 Therefore 3 = a (1) f(1) = ab = 15 3b =15 b =5
f(0) = 3 = a*b0 Therefore 3 = a (1) f(1) = ab = 15 3b =15 b =5 a =3 b =5
f(0) = 3 = a*b0 Therefore 3 = a (1) f(1) = ab = 15 3b =15 b =5 a =3 b =5 f(-2) = 3.5-2 = 3/25
Your answer is: n=-7/2 or n=3/4
Answer:
f(g(x)) = 72x^2+1
Step-by-step explanation:
f(x) = 2x^2 +1
g(x) = -6x
f°g(x) means f(g(x))
Take g(x) and substitute it in for x in f(x)
f(g(x)) = 2(g(x))^2 +1
=2(-6x)^2 +1
=2(36x^2) +1
=72x^2 +1
Answer:
FG=17/4
Step-by-step explanation:
EF+FG=EG
3+x+3=5x+1
x+6=5x+1
6-1=5x-x
4x=5
x=5/4
FG=x+3
FG=5/4 +3
= (5+12)/4
FG=17/4 or 4 1/4 or 4.25
A compound fraction is simplified by multiplying the numerator by the reciprocal of the denominator fraction. This process is repeated as often as necessary at every level of the fraction.
Examples:
(a/b)/(c/d) = (ad)/(bc)
a/(b/c) = (ac)/b
(a/b)/c = a/(bc)

When the fraction has numerators or denominators that are fractions, you need to be very clear about what is being divided by what. If it isn't clear by the typesetting (length or boldness of fraction bars), then parentheses are required around numerators and around denominators.
