Question

evaluate each of the following expressions and function g(x)=-4x power of 2+2x-3 at g(2) and need help on this one toot(n)=2n-11 at t(5)

Answer 1

The fucntion g(x) is given by,

$g(x)=-4x^{2+2x-3}$

Substitute 2 for x to find g(2).

$\begin{gathered} g(2)=-4\ast2^{2+2\ast2-3} \\ =-4\ast2^{2+4-3} \\ =-4\ast2^3 \\ =-4\ast8 \\ =-32 \end{gathered}$

The value of g(2) is -32.

To find t(5) of function t(n)=2n-11, substitute 5 for n in the function.

$\begin{gathered} t(n)=2n-11 \\ t(5)=2\ast5-11 \\ =10-11 \\ =-1 \end{gathered}$

The value of t(5) is -1.
