Web12 aug. 2015 · 1 What I would do is decide that g ( x) = x + h and then perform f composition g f ( g ( x)) = 2 ( x + h) 2 − 3 ( x + h) + 4 which equals f ( g ( x)) = 2 x 2 + 4 x h + 2 h 2 − 3 x − 3 h + 4 I would then input this equation into the difference quotient to get ( 2 x 2 + 4 x h + 2 h 2 − 3 x − 3 h + 4 − ( 2 x 2 − 3 x + 4)) / h After simplifying I get Web9 mrt. 2024 · 1 You have that $f (x+3)=2x^2-3x-1$. Write $y=x+3$, then $x=y-3$ and thus $$f (y)=2 (y-3)^2-3 (y-3)-1=2y^2-15y+26.$$ Hence $f (x+1)=2 (x+1)^2-15 (x+1)+26=2x^2-11x+13$. The key step is to first write $x+3$ as $y$ and change all of the $x$ 's to $y-3$. In this way you rewrite the equation so that you get $f (y)$ in terms of $y$. emissions technical reference energy starWeb分析利用二次函数求出两个函数值相等时，x的值，利用函数的对称性设出函数的解析式，求出函数然后求解函数值．. 解答解：二次函数y=f（x）对一切x∈R恒有x 2-2x+4≤f（x）≤2x 2-4x+5成立，可得x 2-2x+4=2x 2-4x+5，解得x=1，f（1）=3，函数的对称轴为x=1，设函数f（x）=a（x 2-2x）+b， emissions system integrity monitor
