The x-intercepts are the values of x for which f(x) = 0.
x^2 + 4 = 0
x^2 = -4
x= ±√(-4), which are not real numbers. f(x) does not have an x-intercept.
572 rounded to the nearest 10 is 570 and 572 rounded to nearest 100 is 600.
Answer:
Isosceles triangle
Step-by-step explanation:
Answer:
2. This is only true when x=-3.
3. This is only true when x=3.
4. This is only true when x=12.
5. This has no solution.
6. This has an infinite number of solutions.
the equation is the horizontal line which parts through (-5,6), since it has no slope.
