Sketch the graph to find where (1,0) on the parent function maps to on : f(x) = log_1/4(x + 2) - 3

• ( -1, -3)

• ( -2, -3)

• ( -3, -3)

• ( -3, 2)

Express in logarithm form: 5^x+2 = 125

• log₅(x)=123

• log₅(125)=x+2

• log₁₂₅(5)=x+2

• log₁₂₅(x+2)=5

Express in exponential form: log_x-3(7)=12

• (x-3)¹² = 7

• 7¹² = x-3

• 12^x-3 = 7

• (x-3)⁷ = 12

Express in logarithm form: e^x = y

• log(e^y)= x

• log(y) = x

• ln(x)=y

• ln(y)=x
