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

you would use (d.) the law of cosines or a^2 = b^2 + c^2 – 2bc(cos a)

, b^2 = a^2 + c^2 – 2ac(cos b), or c^2 = a^2 + b^2 - 2ab(cos c). you wouldn't use b. the law of sines as it is mostly effective when 1side and 2angles are given. a and c aren't the answer for they are the improper versions of the law of cosines. hope this is .
