2 answers:
Answer:
Option 4th is correct
Infinitely many solution
Step-by-step explanation:
Given the equation:
Subtraction property of equality states that you subtract the same number to both sides of an equation.
Subtract 12 x from both sides we have;
Combine like terms;
True for all x.
⇒Infinitely many solutions can be found for the given equation.

Answer:
See attached image for the graph of the function
Step-by-step explanation:
Notice that this is the product of a power function () times the trigonometric and periodic function cos(x). So the zeros (crossings of the x axis will be driven by the values at which they independently give zero. That is the roots of the power function (only x=0) and the many roots of the cos function:
, and their nagetiva values.
Notice that the blue curve in the graph represents the original function f(x), with its appropriate zeros (crossings of the x-axis), while the orange trace is that of "-f(x)". Of course for both the zeroes will be the same, while the rest of the curves will be the reflection over the x-axis since one is the negative of the other.
