Answer:
Step-by-step explanation:
Given quadratic function is,
f(x) = (x + 6)(x - 3)
For x-intercept,
Substitute the value f(x) = 0.
(x + 6)(x - 3 = 0
x = 3, -6
So the x-intercepts will be,
(-6, 0) and (3, 0)
For y-intercept,
Substitute the value for x = 0,
f(0) = (0 + 6)(0 - 3)
= -18
Therefore, y-intercept of the given quadratic function will be (0, -18).
The first thing we are going to do for this case is define variables.
We have then:
x: number of days
y: number of pages remaining.
We write the linear equation that models the problem:

The intersection with the vertical axis is:
We evaluate x = 0:

We get the point:

The intersection with the horizontal axis is:
We evaluate y = 0:


We get the point:

£36.48.
1. Multiply 38 by 0.04 (4% in decimal) and you’ll get 1.52
2. Subtract 1.52 from 38 to get 36.48
