Question 29

Multiple Choice

Find the derivative of the function. j(x) =7sec⁡2xj ( x ) = 7 \sec ^ { 2 } x


A) j′(x) =14sec⁡2x⋅tan⁡xj '( x ) = 14 \sec ^ { 2 } x \cdot \tan x
B) j′(x) =7sec⁡2x⋅tan⁡xj '( x ) = 7 \sec ^ { 2 } x \cdot \tan x
C) j′(x) =14sec⁡2x⋅tan⁡2xj '( x ) = 14 \sec ^ { 2 } x \cdot \tan ^ { 2 } x
D) j′(x) =−14sec⁡2x⋅tan⁡xj ^ { \prime } ( x ) = - 14 \sec ^ { 2 } x \cdot \tan x
E) j′(x) =14sec⁡x⋅tan⁡xj '( x ) = 14 \sec x \cdot \tan x
