Evaluate when x = 2<br> -X2 + 5x - 7

Rufina [12.5K]

Answer:

Step-by-step explanation:

f(x)=x²-5x+7

f(2)=2²-5.2+7=4-10+7=11-10=1

f(-1)=(-1)²-5.(-1)+7=1+5+7=13

f(1/3)=(1/3)²-5(1/3)+7=1/9-5/3+7=49/9

∴, f(2)-f(-1)+f(1/3)

=1-13+49/9

=58/9-13

=-59/9

Fter completing the fraction division 7/3 : 2/9 , Bai used the multiplication below to check his work.

Vitek1552 [10]

First off all, let's find
$\dfrac{7}{3} : \dfrac{2}{9} = \dfrac{7}{3} \cdot \dfrac{9}{2}= \dfrac{63}{6} = \dfrac{21}{2}$ .

This shows that Bai found the correct quotient.

If $a:b=c$ , then $a=c\cdot b$ . Using this rule, you have to check that $\dfrac{7}{3}$ is equal to product $\dfrac{21}{2} \cdot \dfrac{2}{9}$ .

Thus, Bai checked his work using multiplication correctly.

Answer: Correct choice is A.
