Explanation Given information: f ( x , y ) = 2 x + 3 y , r ( t ) = 〈 t 3 , t 2 〉 , t = − 2 . Calculation: Since the gradient of function is denoted by ∇ f = 〈 ∂ f ∂ x , ∂ f ∂ y 〉 . The given equation f ( x , y ) = 2 x + 3 y Differentiating f with respect to x we get, ∂ f ∂ x = ∂ ∂ x ( 2 x + 3 y ) ⇒ ∂ f ∂ x = 2 Differentiating f with respect to y we get, ∂ f ∂ y = ∂ ∂ y 2 x + 3 y ⇒ ∂ f ∂ y = 3 Hence ∇ f = 〈 ∂ f ∂ x , ∂ f ∂ y 〉 = 〈 2 , 3 〉 Now we have to calculate r ' ( t ) . Since r ( t ) = 〈 t 3 , t 2 〉 Differentiate r ( t ) with respect to t we get, r ' ( t ) = d d t 〈 t 3 , t 2 〉

Given the graph of f(x) below. Determine the average rate of change of f(x) from x = -2 to x = 2. Give your answer as a simplified fraction if necessary. For example, if you found that msec = , you would enter 3 2 2 3 X 23

A function is defined on the interval (-π/2,π/2) by this multipart rule: if -π/2 < x < 0 f(x) = a if x=0 31-tan x +31-cot x if 0 < x < π/2 Here, a and b are constants. Find a and b so that the function f(x) is continuous at x=0. a= b= 3

Use the definition of continuity and the properties of limits to show that the function is continuous at the given number a. f(x) = (x + 4x4) 5, a = -1 lim f(x) X--1 = lim x+4x X--1 lim X-1 4 x+4x 5 ))" 5 )) by the power law by the sum law lim (x) + lim X--1 4 4x X-1 -(0,00+( Find f(-1). f(-1)=243 lim (x) + -1 +4 35 4 ([ ) lim (x4) 5 x-1 Thus, by the definition of continuity, f is continuous at a = -1. by the multiple constant law by the direct substitution property
