(6/2) - 4 would be your answer
Step-by-step explanation:
I take it this is meant to be a multiplication, right ?
not a "function of function", which would be symbolized by a little empty circle.
to multiply 2 function means basically the same as to add, subtract or divide 2 functions : to apply the arithmetic operation in both expressions.
(f×g)(x) = (-2x² + 4x)(x² + 18x + 77) =
= -2x⁴ - 36x³ - 154x² + 4x³ + 72x² + 308x =
= -2x⁴ - 32x³ - 82x² + 308x
First you must distribute the 2 to the numbers inside the parentheses, which would be 1 and -x...
(2 * 1) + (2 * -x) > 2x
2 + (-2x) > 2x
2 - 2x >2x
Add 2x to both sides (what you do on one side you must do to the other). Since 2x is being subtracted, addition (the opposite of subtraction) will cancel it out (make it zero) from the left side and bring it over to the right side.
2 - 2x + 2x > 2x + 2x
2 + 0 > 4x
2 > 4x
Next divide 4 to both sides to finish isolating x. Since 4 is being multiplied by x, division (the opposite of multiplication) will cancel 4 out (in this case it will make 4 one) from the right side and bring it over to the left side.
2/4 > 4x / 4
1/2 > x
or
x < 1/2
Hope this helped!
