Integrate 1/(cos(x)2) from 0 to 2pi;Find f'(a) f(x) = 3x^2 4x 1 💬 👋 We're always here Join our Discord to connect with other students 24/7, any time, night or dayIf f(x) = 3x 4, find f(5) and f(x 1) f(5) = 3(5) 4 = 19 f(x 1) = 3(x 1) 4 = 3x 7 Domain and Range The domain of a function is the set of values which you are allowed to put into the function (so all of the values that x can take) The range of the function is the set of all values that the function can take, in other words all
4 Another, more mechanical approach First of all, just by counting degrees it's clear that any polynomial solution f must be quadratic, so we can write f(x) = ax2 bx c What's more, plugging in x = 0 gives 02 ⋅ f(0) f(1) = 2 ⋅ 0 − 04, or f(1) = 0, and plugging in x = 1 gives 12 ⋅ f(1) f(0) = 2 ⋅ 1 − 14, or f(0) = 1, so we know that c = 1 and a b c = 0, or b = − (1 a)1 Example 1 f(x) = x We'll find the derivative of the function f(x) = x1 To do this we will use the formula f (x) = lim f(x 0 0) Δx→0 Δx Graphically, we will be finding the slope of the tangent line at at an arbitrary point (x 0, 1 x 1 0) on the graph of y = x (The graph of y = x 1 is a hyperbola in the same way that the graph of Transcript Ex 51, 8 Find all points of discontinuity of f, where f is defined by 𝑓(𝑥)={ (𝑥/𝑥, 𝑖𝑓 𝑥≠0@&0 , 𝑖𝑓 𝑥=0)┤ Since we need to find continuity at of the function We check continuity for different values of x When x = 0 When x > 0 When x < 0 Case 1 When x = 0 f(x) is continuous at 𝑥 =0 if LHL = RHL = 𝑓(0) Since there are two different
Assuming that f is nonzero, we can rewrite this equation as 1 f(x) 1 f(1 / x) = 1 Making the substitution g(y) = − 1 2 1 f ( ey), we get the functional equation g(y) g( − y) = 0, which simply says that g is odd This equation can be solved, with the initial condition, by setting g(y) = cy for a suitable constant c Find the derivative of the following via implicit differentiation d/dx(f(x)) = d/dx(1/(1x^2)) The derivative of f(x) is f'(x) f'(x) = d/dx(1/(1x^2)) Ex 13, 6 Show that f −1, 1 → R, given by f(x) = 𝑥/(𝑥 2) is oneone Find the inverse of the function f −1, 1 → Range f (Hint For y ∈ Range
