Question

Evaluate f(x) = x4 - 7x2 + 2x - 6 at x = 1

Answer 1

Answer:

if X=1

Step-by-step explanation:

(1)^4-7(1)^2+2(1)-6

1-7+2-6

-6-4

=-10

Answer 2

SOLUTION

GIVEN

$\sf{f(x) = {x}^{4} - 7 {x}^{2} + 2x - 6 }$

TO DETERMINE

The value of f(x) at x = 1

EVALUATION

Here it is given that

$\sf{f(x) = {x}^{4} - 7 {x}^{2} + 2x - 6 }$

Putting x = 1 in both sides we get

$\sf{f(1) = {(1)}^{4} - 7 \times {(1)}^{2} + 2 \times (1) - 6 }$

$\sf{ \implies \: f(1) = 1 - 7 + 2 - 6}$

$\sf{ \implies \: f(1) = 3 - 13}$

$\sf{ \implies \: f(1) = - 10}$

FINAL ANSWER

The value of f(x) at x = 1 is - 10
