2017年10月8日 · How do you find #f(g(-3))# given #f(x)=2x-1# and #g(x)=3x# and #h(x)=x^2+1#? Algebra Expressions, Equations, and Functions Function Notation

2016年5月19日 · Alright, Yanet, (f-g)(x) means we are going to subtract the two functions. (f-g)(3) means we are then going to plug in 3 for each x and solve. We can also do it reversed.

If f(x) = 1 - x 3 and g(x) = x + 5, then fg(3) = ? I do not need to show my work. I just need the answer ...

2017年4月3日 · Compute (f-g)(x) and then evaluate at x = 3 OR Evaluate f(3)" and "g(3) and then perform the subtraction. (f-g)(3) = f(3)-g(3) Compute (f-g)(x): (f-g)(x) = f(x) - g(x ...

2019年10月4日 · g(3)= 3 +1 = 4. Then you will substitute 4 into where g(3) was in your original problem. f( g(3) )= f( 4 ) = 2(4)-3=5. So (f of g)(3)=5 *You can also think of it as plugging 3 into the function closest to it first then plug that answer into the farther function. Since g was closer, we plugged 3 into g(x) and took its answer and plugged it into ...

2017年1月19日 · f(g(3))=3 As g(3)=2 f(g(3))=f(2) but f(2)=3 Hence f(g(3))=3. What are some common mistakes students make with function composition?

2013年11月18日 · For the 2 functions, f (x) and g(x), tables of values are shown below. What is the value of g(f (3)) ? x ¦f(x) x ¦g(x)
