For the graph of the function, identify the axis of symmetry, vertex and the formula for the function.
Axls of symmetry: x = -0.5; Vertex: (-0.5, -0.5); f(x) = -2x2 - 2x - 1
Axis of symmetry: x = 0.5; Vertex: (0.5, -0.5); f(x) = 2x2 - 2x - 1
Axis of symmetry: * = -0.5; Vertex: (-0.5, 0.5); M(x) = -2x2 + 2x - 1
Axis of symmetry: x = -0.5; Vertex: (-0.5, -0.5); M(x) = -2x2 + 2x - 1

answer: 1 and 3

step-by-step explanation:

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

can you make your screen more see able?

then i might be able to .

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
