Use synthetic substitution to find g(4) and g(-5) for the function g(x) = 3x4 - 5x2 + 7x - 7

nevsk [136]

Answer:

$g(4)=709$

$g(-5) = 1708$

Step-by-step explanation:

Substitution Method:

$g(4)=3(4)^4-5(4)^2+7(4)-7$

$g(4)=3(256)-5(16)+28-7$

$g(4)=768-80+28-7$

$g(4)=709$

Synthetic Division:

$\begin{array}{rrrrrr}\multicolumn{1}{r|}{4} & {3} & 0 & -5 & 7 & -7\\\cline{2-6} & & 12& 48 & 172 & 716\\\cline{2-6} & 3 & 12& 43 & 179 & \multicolum{|} 709\end{array}$

Answer: $g(4)=709$

$g(-5)=3(-5)^4-5(-5)^2+7(-5)-7$

$g(-5)=3(625)-5(25)-35-7$

$g(-5) = 1875-125-35-7$

$g(-5) = 1708$

Synthetic Division:

$\begin{array}{rrrrrr}\multicolumn{1}{r|}{-5} & {3} & 0 & -5 & 7 & -7\\\cline{2-6} & & -15& 75& -350& 1715\\\cline{2-6} & 3 & -15& 70& -343& \multicolum{|} 1708\end{array}$

Answer: $g(-5) = 1708$

Complete the statements. If both expressions have the same value after substituting and simplifying two different values for the

8_murik_8 [283]

When both expressions have the same value, then they are equal to each other.

<h3>What is an equivalent expression?</h3>

The equivalent is the expressions that are in different forms but are equal to the same value.

Consider the expressions 5 + 8k and 8k + 5.

Using k = 3

5 + 8k = 8k + 5

5 + 8(3) = 8(3) + 5

5 + 24 = 24 + 5

29 = 29

Using k = 5

5 + 8k = 8k + 5

5 + 8(5)= 8(5) + 5

5 + 40 = 40 + 5

45 = 45

Learn more about the equivalence on:

<u>Complete question:</u>

Consider the expressions 5 + 8k and 8k + 5. Determine why the expressions are equivalent.

Using k = 3 5 + 8k 8k + 5 5 + 8(3) 8(3) + 5 5 + 24 = 29 24 + 5 = 29

Using k = 5 5 + 8k 8k + 5 5 + 8(5) 8(5) + 5 5 + 40 = 45 40 + 5 = 45

Complete the statements.

If both expressions have the same value after substituting and simplifying two different values for the variable, then they are.

The value of both expressions when k = 3 is and when k = 5 is 45, so the expressions are.
