The equation for a function is
f(x) = x + b

So consider this example function:
f(4) = 3x + 12
We know that x = 4 so we would substitute 4 for x.
f(4) = 3(4) + 12
f(4) = 12 + 12
f(4) = 24

Since f(x) is equivalent to y, you could also say;
f(4) = y
y = 24

Answer:

Step-by-step explanation:

$f(x)=4x^2+4x-4\ or\ f^*(x)=4x+4x-4=8x-4\\\\f(0)-\text{put}\ x=0\ \text{to}\ f(x):\\\\f(0)=4(0)^2+4(0)-4=4(0)+0-4=0-4=-4\\\\f^*(0)=8(0)-4=0-4=-4$

Each of 8 students reported the number of movies they saw in the past year. This is what they reported: 4, 14, 16, 4, 20, 19, 12

marysya [2.9K]

The mean is simply the average of the total movies seen so..
$\frac{4 + 14 + 16 + 4 + 20 + 19 + 12 + 10}{2} = mean$
$\frac{99}{2} = mean$
$49.5 = mean$

the median is the middle number (or the average of the middle 2 numbers)
so if we line up the numbers in order and cross them out from both ends we get 12 & 14 so we take the average of the 2
$13 = median$
