Question

What is value of f (-3/2) when f (x)= X²-4x+7

Answer 1

Step-by-step explanation:

If f(x)=x

2

−4x+3

F(2)=2

2

−4(2)+3

=4−8+3

=−4+3

=−1

F(1)=(1)

2

−4+3

=1−4+3−3+3

=0

F(2)−F(1)

=−1+0

=−1

The value of f ( $\sf\frac{-3}{2}$ ) is $\sf\frac{61}{4}$

Step by step explanation:

Given :

The value of f ( $\sf\frac{-3}{2}$ )

When f ( x ) = x² - 4x + 7

Solution :

According to the question the value of x here is given as $\sf\frac{-3}{2}$ ,

To get the solution we should substitute the value of x in the given statement ,

• f ( x ) = x² - 4x + 7

• f ( $\sf\frac{-3}{2}$ ) = $\sf{\frac{-3}{2}}^2[/Tex] - 4([tex]\sf\frac{-3}{2}$) + 7

• $\sf\frac{9}{4}$ + 6 + 7

• $\sf\frac{9}{4}$ + 13

• $\sf\frac{9}{4}$ + $\sf\frac{13}{1}$

• Take LCM of 1 and 4 that is 4

• $\sf\frac{9}{4}$ + $\sf\frac{13\:\times\:4}{1\:\times\:4}$

• $\sf\frac{9}{4}$ + $\sf\frac{52}{4}$

• $\sf\frac{9\:+\:52}{4}$

• $\sf\frac{61}{4}$
