Given the following function, find the x and y intercepts (from left to right), vertex, and axis of symmetry. Function: f(x)=(x+2)(x−4)

Axis of symmetry for y = ax² + bx + c is,

a = - 4/5, b = 48/5

So, x = - 48/5 × - 5/8

Now, Vertex:

NOTE: See picture attached.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
