Answer:
; minimum
Step-by-step explanation:
Given:
The function is, 
The given function represent a parabola and can be expressed in vertex form as:

The vertex form of a parabola is
, where,
is the vertex.
So, the vertex is
.
In order to graph the given parabola, we find some points on it.
Let 




So, the points are
.
Mark these points on the graph and join them using a smooth curve.
The graph is shown below.
From the graph, we conclude that at the vertex
, it is minimum.
Answer:

Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the function
y = f(x) = 3 x ( 4 x + 7)
y = 3 x ( 4 x + 7)
y = 12 x² + 21 x ..(i)
Differentiating equation (i) with respective to 'x' , we get


Answer:
3rd option
Step-by-step explanation:
Given
x³ - 7x² - 5x + 35 ( factor the first/second and third/fourt terms )
= x² (x - 7) - 5(x - 7) ← factor out (x - 7) from each term
= (x² - 5)(x - 7)
2 dogs/ 3 cats and 10 dogs/ 15 cats are an example of
b. Equivalent ratios
__________________________

We can see that they are equivalent ratios.
2 to the 3rd power (2^3) times x to the second (x^2)
