The composite functions of higher math often use h(x) and g(x), in combination,,defining which comes first, and which is second. The substitution is bad enough, but using y's would make it worse.. In summary, feel free to immediately use "y =" instead of "h(x)", if it clarified the problem.

2011年4月30日 · g(x) just identifies a function of x, in the same way as that f(x) does. Using a "g" instead of an "f" only means the function has a different label assigned to it. Typically this is done where you have already got an f(x), so creating another one would be confusing. you can use any letter you like (i wouldn't use x, though): eg: f(x) = 2x+1 g ...

since g(x) = x^2 + 3, you get: f(g(x)) = sqrt(x^2 + 3) + 8 when x = 3, you get: f(g(x)) = sqrt(3^2 + 3) + 8 = 11.46410162 this is equivalent to finding g(x) first and then finding f(g(x)). g(x) = x^2 + 3. when x = 3, g(x) = 3^2 + 3 = 12. f(g(x)) becomes f(12) = sqrt(12) + 8 = 11.46410162. f(x) and g(x) are repeated here to make them easier to ...

You can put this solution on YOUR website! g(x+h)=2-(x+h)^2=2-x^2-2xh-h^2 g(x)=2-x^2 subtracting, =-2xh-h^2 divide that by h and get -2x-h

The remainder when a polynomial p(x) is divided by the linear polynomial x-a is the polynomial evaluated at a, p(a). In this example, p(1) = 1 -14 +18 +72 = 77. So "77/(x-1)" COULD be considered the remainder; but in most contexts the remainder would be just "77".

Question 774320: Suppose that the functions f and g are defined as follows f(x)=(1)/(5x^(2)+4) g(x)=(1)/(√(3x+5)) Find f*g and f+g . Then, give their domains using interval notation. (f*g)(x)= domain of f*g = (f+g)(x)= domain of f+g = Any help would be appreciated. Thank you Answer by oscargut(2103) (Show Source):

2008年11月9日 · If f'(x) and g'(x) exist and f'(x) > g'(x) for all real x, then the graphs of y = f(x) and y = g(x)... Came up on my calculus test, and it's the only one I...

Question 1168373: Let f(x)= 3|x| If g(x)is the graph of f(x) shifted right 4 units, write a formula for g(x)

The function g is related to one of the parent functions g(x) = x^2 + 6 The parent function f is: f(x)= x^2 Use function notation to write g in terms of f. Algebra -> Coordinate Systems and Linear Equations -> SOLUTION: 1.)
