Answer:
You can use dots, tallys or pictures
Step-by-step explanation:
When x = 1:
1³ + 1 - 3 = -1
When x = 2:
2³ + 2 - 3 = 7
Since f(x) = x³ + x - 3 is continuous, it follows from the intermediate value theorem that for some c in the interval (1, 2), we have f(c) = 0, since f(1) < 0 < f(2).

Answer:
Step-by-step explanation:
Simplifying
2x(3 + 4a) = -16x + 6x
(3 * 2x + 4a * 2x) = -16x + 6x
Reorder the terms:
(8ax + 6x) = -16x + 6x
(8ax + 6x) = -16x + 6x
Combine like terms: -16x + 6x = -10x
8ax + 6x = -10x
Solving
8ax + 6x = -10x
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-6x' to each side of the equation.
8ax + 6x + -6x = -10x + -6x
Combine like terms: 6x + -6x = 0
8ax + 0 = -10x + -6x
8ax = -10x + -6x
Combine like terms: -10x + -6x = -16x
8ax = -16x
Divide each side by '8x'.
a = -2
Simplifying
a = -2 <— answer
