Think about it... if the number is bigger than 5 you round up so.. 399 is rounded to 400.
f(x) has vertex = (- 1, - 5 ) and is a minimum
g(x) has vertex = (2, 3 ) and is a maximum
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
f(x) = (x + 1)² - 5 is in this form with vertex = (- 1, - 5 ) and minimum
to determine if maximum/ minimum
• if a > 0 then minimum
• if a < 0 then maximum
g(x) = - (x - 2)² + 3 is also in vertex form with a < 0
vertex = (2, 3 ) and is a maximum
Answer:
71 (or 7.... read explanation)
Step-by-step explanation:
If you mean | -71 | then it's 71.
If you mean | -7 | then it's 7
Absolute values turn negative numbers into positive numbers.
Since we know the cube of 2 is 8 and the cube of 3 is 27, we know it must be between these two numbers, and since 25 is much closer to 27 than it is to 8, we can say the closest integer is 3.
Answer:
Step-by-step explanation:
the only difference i can think of is that x = 0 is actually saying that 0 is a solution. f(0) is just asking you to plug in zero for x, rather than saying it is the actual solution.
