Realize the tangent function has a period of 180°, so when your calculator (or memory) tells you
.. θ = arctan(-1)
.. θ = -45°
you can translate that value into the desired range by adding multiples of 180° to get the two solutions ...
.. θ = 135°
.. θ = 315°

What are the maximum and minimum of the function f(x) = 0.9|-(x − 5)| + 7?
r-ruslan [8.4K]

Answer:

Maximum value:

the maximum value is \infty

Minimum value:

the minimum value is 7

Step-by-step explanation:

We are given function as

f(x)=0.9|-(x-5)|+7

Firstly, we will draw graph

we can see the graph

and then we can identify maximum and minimum

Maximum value:

We know that

the largest y-value means maximum value of f(x)

We can see that curve is moving upward

so, the maximum value is \infty

Minimum value:

We know that

the smallest y-value means minimum value of f(x)

we can see that

It starts from point (5,7)

so, the minimum value is 7
