Answer:
Step-by-step explanation:
In each case, the axis of symmetry is the vertical line through the vertex.
<u>For f(x)</u>
The equation is in vertex form:
f = a(x -h)² +k . . . . has vertex (h, k)
The x-coordinate of the vertex can be read from the equation: 4. The vertical line with that x-coordinate is ...
x = 4
__
<u>For h(x)</u>
The vertex is the point where the graph reaches a maximum, (-2, 2). The vertical line with that x-coordinate is ...
x = -2
Answer:
a. 18
b. 45
Step-by-step explanation:
The question states that 2/5 of the class are girls which means 3/5 are boys:
Divide this value by 3 to get the value of 
:
27 ÷ 3 = 9
Multiply this by 5 to find 
, the total pupils in the class:
9 x 5 = 45
As the number of girls is 
of the total pupils:
9 x 2 = 18
So there are 18 girls in the class which has a total pupil size of 45.
Hope this helps!
