You need only two points to graph a linear function. These points may be chosen as the x and y intercepts of the graph for example. Determine the x intercept, set g(x) = 0 and solve for x. 0=2x-1 1=2x x=1/2 Determine the y intercept, set x = 0 to find f(0). g(0)=2(0)-1 y=-1 (1/2,0) (0,-1)

2016年12月28日 · g(g(x)) = 4x + 3 Simply input g(x) into g(x). g(g(x)) = 2(2x + 1) + 1 =4x + 2 +1 = 4x +3 Hopefully this helps!

2018年2月17日 · g(x+1)=(x^2+2x+1)(x-1) A function takes in an input and returns an output. In this function g(x), you input x and it returns x^3-2x^2. We can also look at this as this: you input x (what's enclosed by the parentheses) and this function g(x) takes the input (x), cubes it (x^3), subtracts two times the input squared (-2x^2). Putting this all …

Question 24562: Given that g(x)=3x^2-2x+1, find each of the following: g(0) g(3) g(1-t) g(-1) g(-x) I haven't been in Algebra in 13 years. The teacher suggested that I go back to basic, but I am determined to pass this class. I appreciate any help you …

2016年1月8日 · In this problem, ƒ o g o h = ƒ(g(h(x))) Start out by plugging h into g. ƒ(g(x^2))) =ƒ(3(x^2) + 1) = ƒ(3x^2 + 1) Next, plug in the new function into ƒ. = (3x^2 + 1 - 2) / (2(3x^2 + 1) + 1) = (3x^2 - 1) / (6x^2 + 3)

2018年6月20日 · Here, #color(red)(f(x)=2x+1...to(1) and g(x)=x-3....to(2)# We assume that , #R_fsube D_g and gof # exist. #gof(x)=g(f(x))#

2018年4月30日 · How do you verify if #f(x)=2x-4; g(x)=1/2x+2# are inverse functions? Precalculus Functions Defined and Notation Function Composition. 1 Answer

g(f(x)) means that the function g is composed at the function f. You need to plug the value of f(x) into the function g and simplify. g(x) = 2x - 1 Replace x with the value of f(x) which is 3x - 2 and simplify. g(f(x)) = 2x - 1 g(3x - 2) = 2(3x - 2) - 1 g(3x - 2) = 6x - 4 - 1 g(3x - 2) = 6x - …
