Question

Select Yes or No for each function to tell whether the function is exponential or not Function

f(x)=x^3

f(x)=2*3^x

f(x)= 3*1/2x

f(x) = 1.003^x

f(x) = 3*x^2

f(x)= 1/10*4^x

Answer 1

given below

Explanation:

f(x)=x^3 = polynomial function

f(x)=2*3^x = exponential exponential

f(x)= 3*1/2x = linear function

f(x) = 1.003^x = Exponential function

f(x) = 3*x^2 = Quadratic function

f(x)= 1/10*4^x = Exponential functions

Answer 2

• B, D, F - yes
• A, C, E - no

Explanation:

Exponential function is:

• f(x) = abˣ

Verify the given functions:

• A. f(x)=x³ ⇒ No, cubic function
• B. f(x)=2*3ˣ ⇒ Yes
• C. f(x)= 3*1/2x ⇒ No, linear function
• D. f(x) = 1.003ˣ ⇒ Yes
• E. f(x) = 3*x² ⇒ No, quadratic function
• F. f(x)= 1/10*4ˣ ⇒ Yes
