The graph of a function in the form f(x) a(x - h)2 +k is shown. Use the graph to find an equation for f(x).

seropon [69]

O.K.

(h; k) are the coordinates of the vertex.

On the graph are (3; 4), therefore we have:

$f(x)=a(x-3)^2+4$

We have the x-intercept (1; 0) → x = 1; y = 0.
Substitute them in the equation:

$0=a(1-3)^2+4\\\\0=a(-2)^2+4\\\\4a+4=0\ \ \ |-4\\\\4a=-4\ \ \ \ |:4\\\\a=-1$

so. We have the answer:

$\boxed{f(x)=-(x-3)^2+4}$

A 7th grade math class is having a year end party. So far, 16 students have paid a total of $132.

krek1111 [17]

Answer:

A) 8.25c + 25s = 206.25

B)This contribution affects the equation because it adds money and a person and because she is adding more than the normal amount that each student pays

Step-by-step explanation:

132/16= 8.25

each student paid $8.25

A sequence is defined by the recursive formula f (n 1) = f(n) – 2. if f(1) = 18, what is f(5)?

Marat540 [252]

Would assume:

f(n + 1) = f(n) - 2

f(2) = f(1 + 1) = f(1) - 2 = 18 - 2 = 16

f(3) = f(2 + 1) = f(2) - 2 = 16 - 2 = 14

f(4) = f(3 + 1) = f(3) - 2 = 14 - 2 = 12

f(5) = f(4 + 1) = f(4) - 2 = 12 - 2 = 10

f(5) = 10
