Pre Calc work, I need help with writing piece wise functions from graphs. Can anyone help? Giving brainliest
Andrei [34K]

The definition of the piece-wise function is:

  • f(x) = 2.5x + 1, -2 \leq x \leq 2
  • f(x) = -3, 2 < x < 6.

<h3>What is a piece-wise function?</h3>

A piece-wise function is a function that has different definitions, depending on the input.

In this problem, for inputs between -2 and 2, the function is a line that goes through (-2,-4) and (2,6). The slope is:

m = (6 - (-4))/(2 - (-2)) = 2.5.

The y-intercept is of b = 1, hence the rule is:

f(x) = 2.5x + 1, -2 \leq x \leq 2

For x greater than 2 and less than 6, the function is constant at -3, hence the rule is:

f(x) = -3, 2 < x < 6.

Find the product.<br><br> 8y^3(-3y^2)<br><br> __ Y----
ivanzaharov [21]

Answer:

y= 12

Step-by-step explanation:

8y x 3(-3y x 2)

By multiplying 3 inside the bracket values

= 8y x -9y x 6

By multiplying the same polynomials co-coefficients

= -72y x 6

y x 6 =72

By Shifting the negative term to the other side

y = 72/6

By dividing

y= 12

Hypotenuse = 8

Height = h

Adjacent :

=  \frac{10}{5}  = 2

Height, h :

{ \tt{h =  \sqrt{ {8}^{2}  -  {5}^{2} } }} \\ { \tt{h =  \sqrt{64 - 25} }} \\ { \tt{h =  \sqrt{39} }} \\ the \: height \: is \: { \boxed{6.2}} \: units
