Which of the following are exponential functions? Select all correct answers.

Select all that apply:

a) f(x)=4(1/4)^x
b) g(x)=14(4)^x
c) h(x)=10x^5
d) j(x)=−9x^4
e) k(x)=6(5.49)^x

a) f(x)=4(1/4)^x

b) g(x)=14(4)^x

e) k(x)=6(5.49)^x

Step-by-step explanation:

If x is in the exponent(that is, something elevated to x), it is an exponential function.

Otherwise, if x is in the base(that is, x elevated to something), it is a polynomial function.

a) f(x)=4(1/4)^x

x in the exponent, so exponential

b) g(x)=14(4)^x

x in the exponent, so exponential

c) h(x)=10x^5

x in the base, so polynomial

d) j(x)=−9x^4

x in the base, so polynomial

e) k(x)=6(5.49)^x

x in the exponent, so exponential

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this

step-by-step explanation:

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
