BL Srivastava Answered 2 years ago Author has 46K answers and 21M answer views This is simple provided you know about the composition of functions Here f (x) = 2x 5 = y (let), then g (f (x)) = g (y) = cos (y/2) 3y = cos ( (2x 5)/2) 3 (2x 5) = cos (x 5/2) 6x 15 114K viewsIf a horizontal line intersects the graph of f(x) in more than one point, then f(x) is not onetoone The reason f(x) would not be onetoone is that the graph would contain two points that have the same second coordinate – for example, (2,3) and (4,3) That would mean that f(2) and f(4) both equal 3, and onetoone0 votes 1 answer Let u be a vector coplanar with the vectors a=2i3jk and vector b= jk If vector u is perpendicular to vector a and vector ub=24,

Or the value of the function evaluated at 2x Giving a name f to a function for the function using independant variable x will be named as f (x), to be read, "the function f of x" Shown alone, f and x are not factors, but are a complete nameL'Hopital's Rule Consider the limit lim x → a f(x) g(x) If both the numerator and the denominator are finite at a and g(a) ≠ 0, then lim x → a f(x) g(x) = f(a) g(a) lim x → 3 x2 1 x 2 = 10 5 = 2 But what happens if both the numerator and the denominator tend to 0?F(g(x))=(1/x1)21 No solutions found Rearrange Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation f(g(x))=(1/x1)21 No solutions found Rearrange Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation

The answer is x^39x^227x29First, take (x3) and plug it into F(x) From that you break up (x3)^3 into three binomial because it is a 3 degree, and then you tack the 2 along sideIn this video we learn about function composition Composite functions are combinations of more than one function In this video we learn about f(g(x)) and gEvery element x of GF(2) satisfies x 2 = x (ie is idempotent with respect to multiplication);

To find the answers, I can either work symbolically (like in the previous example) and then evaluate, or else I can find the values of the functions at x = 2 and then work from there It's probably simpler in this case to evaluate first, so f (2) = 2 (2) = 4 g (2) = (2) 4 = 6 h (2) = 5 – (2) 3 = 5 – 8 = –3Use "x" as the variable like this Examples sin(x) 2x−3;Axis of Symmetry x = 2 x = 2 Directrix y = −9 4 y = 9 4 Select a few x x values, and plug them into the equation to find the corresponding y y values The x x values should be selected around the vertex Tap for more steps Replace the variable x x with 1 1 in the expression f ( 1) = ( 1) 2 − 4 ⋅ 1 2 f ( 1) = ( 1) 2 4 ⋅ 1 2
