Answer:

see explanation

Step-by-step explanation:

(a)

The zeros are x = 1 and x = 5, thus the factors are (x - 1) and (x - 5)

f(x) = a(x - 1)(x - 5)

To find a substitute (0, 15), the coordinates of the y- intercept into the equation.

15 = a(0 - 1)(0 - 5) = a(- 1)(- 5) = 5a ( divide both sides by 5)

a = 3

Thus h = 1, k = 5, a = 3 and

f(x) = 3(x - 1)(x - 5)

(b)

The axis of symmetry is a vertical line with equation x = c ( c is a constant )

The axis of symmetry passes through the midpoint of the zeros

x = \frac{1+5}{2} = \frac{6}{2} = 3

Equation of axis of symmetry is x = 3

(c)

The axis of symmetry passes through P, with x- coordinate x = 3

Substitute x = 3 into the function for corresponding value of y

f(3) = 3(3 - 1)(3 - 5) = 3(2)(- 2) = - 12

Coordinates of  P = (3, - 12 )

Simplify: ⅕y - ⅗y + 5 - ⅖y - 8<br> pls
MrRissso [65]

Answer:

The answer is -(4/5)y - 3.

Step-by-step explanation:

The steps are :

\frac{1}{5} y -  \frac{3}{5} y + 5 -  \frac{2}{5} y - 8

= ( \frac{1 - 3 - 2}{5} y) + (5 - 8)

=  -  \frac{4}{5} y - 3
