10c^4 * 4 c^2
40 c^2
we need to know the value of c to evaluate
<u>Given</u><u> </u><u>:</u><u>-</u>
- The roots of the function are 5 and -3 .
<u>To</u><u> </u><u>Find</u><u> </u><u>:</u><u>-</u>
<u>Answer</u><u> </u><u>:</u><u>-</u>
The roots of the function are 5 and -3 . In general we can write the Quadratic function with roots π and ∆ as ,
f(x) = ( x - π )(x-∆)
So on using this we have ,
f(x) = ( x -5)( x -(-3))
f(x) = (x-5)(x+3)
f(x) = x(x-5)+3(x-5)
f(x) = x² -5x +3x -15
f(x) = x² -2x -15
<u>Hence </u><u>the</u><u> required</u><u> </u><u>answer</u><u> </u><u>is </u><u>x²</u><u> </u><u>-2x </u><u>-</u><u>1</u><u>5</u><u>.</u>
The central angle is 77 degrees mate.
Answer:
f(-2)=-9
Step-by-step explanation:
Since x=-2, therefore you would replace x with -2 with the equation provided.
f(-2)=4(-2)-1
f(-2)=-8-1
f(-2)=-9
