Given that $y=u^3$y=u3 and $u=2x+3$u=2x+3, define $y$y in terms of $x$x. Leave your answer in factored form.
Consider the function $f\left(x\right)=\left(5x^3-4x^2+3x-5\right)^7$f(x)=(5x3−4x2+3x−5)7.
Redefine the function as composite functions $f\left(u\right)$f(u) and $u\left(x\right)$u(x), where $u\left(x\right)$u(x) is a polynomial.
Consider the function $f\left(x\right)=\sqrt[4]{2x^2+2x+3}$f(x)=4√2x2+2x+3.
Redefine the function as composite functions $u\left(x\right)$u(x) and $f\left(u\right)$f(u), where $u\left(x\right)$u(x) is a polynomial.
Consider the function $f\left(x\right)=\frac{1}{\left(4x^2-3x+5\right)^3}$f(x)=1(4x2−3x+5)3.
Redefine the function as composite functions $f\left(u\right)$f(u) and $u\left(x\right)$u(x), where $u\left(x\right)$u(x) is a polynomial.
