Question

F(x) = 5x² - 4x – 8; f(0.1) ​

Answer 1

Answer:

4+4√11/10 ,4-4√11/10 answer

Answer 2

SOLUTION

GIVEN

F(x) = 5x² - 4x – 8

TO DETERMINE

F(0.1)

EVALUATION

Here the given function is

F(x) = 5x² - 4x – 8 - - - - - - (1)

We have to find the value of F(0.1)

Putting x = 0.1 in Equation 1 we get

F(0.1)

$\sf{ = 5 \times {(0.1)}^{2} - (4 \times 0.1) - 8 }$

$\sf{ = (5 \times 0.01) - 0.4 - 8 }$

$\sf{ = 0.05 - 0.4 - 8 }$

$\sf{ = 0.05 - 8.4 }$

$\sf{ = - 8.35}$
