You would just replace x with 2 in the part equation and solve for it. So 3(2) - 7. This is equal to -1
.1 repeating is 1/9, so either write it as 12 1/9, or 109/9
Answer:
x is less than or equal to 29
Step-by-step explanation:
-49 <_ 9 - 2x
isolate the variable.
-49 - 9 <_ 9 - 2x - 9
-58 <_-2x
-58/-2 <_-2x/-2
When dividing or multiplying by negatives, flip the sign.
-58/-2 <_-2x/-2
29 >_ x
x <_ 29
x is less than or equal to 29
Assuming the function is
f(x) = x^4 + 3x^3-28x^2
Factorising, we get
f(x) = x^2(x+7)(x-4)
Therefore, there is a double root at x = 0 and singular roots at x = -7 and 4
double roots tend to bounce, kind of like the standard quadratic y = x^2
singular roots tend to cross, kind of like a straight line on a graph, y = mx + b
Therefore, it bounces at x = 0, and crosses at x = -7 and 4
In general, a root raised to an even power bounces, and a root raised to an odd power crosses.
