AA C&C QUIZ -Functions: Cmposition, Inverses, Expntl & Log

Match each logarithmic expression to its equivalent exponential form.

• e^x ≈ 10

• log_x 4 = 10

• 4^x = 10

• ln 10 ≈ x

• e¹⁰ ≈ x

• log x = 4

• x¹⁰ = 4

• ln x ≈ 10

• 10⁴ = x

• log₄ 10 = x

Convert 3⁴ = 81 to its logarithmic form

Given log₅ 0.04 = x,

Complete the steps to evaluate by using exponential form.

​Step 1 (Rewrite in exponential form): ​ (a)   = 0.04

Step 2 (rewrite the decimal as a fraction): 0.04 = ​ (b)  

Step 3 (reduce the fraction): ​ (c)   Step 4 (rewrite as an exponent): ​ (d)  

Answer: ​ (e)  

Given

f(x) = –5x–2
