Answer:

a)  4(t - r) = 4(6 - 2.5) = 4 x 3.5 = 14

b)  4t - r = (4 x 6) - 2.5 = 24 - 2.5 = 21.5

c)  2(3t - 10) = 2(3 x 6 - 10) = 2(18 - 10) = 2 x 8 = 16

d)  (t - 2)² = (6 - 2)² = 4² = 4 x 4 = 16

e) cannot decipher the equation

f)  6r + t = 6 x 2.5 + 6 = 15 + 6 = 21

What's the inverse of f(x)=3x^2+6?
djyliett [7]
Switch where the x and y are, then solve for y. f(x) = y.

x = 3y^2 + 6

x-6 = 3y^2

(x-6)/3 = y^2

f^-1(x) = y = sqrt((x-6)/3)

Tysm for the help! <3

By using the given graph:

  • When x = -2, the value of the function is f(-2) = 1
  • When x = -0.5, the value of the function is f(-0.5) = 0.75
  • When x = 0, the value of the function is f(0) = 1.25
  • When x = 2.5, the value of the function is f(2.5) = 3
  • When x = 6, the value of the function is f(6) = 0
<h3></h3><h3>How to use the graph to find the values of the function?</h3>

Suppose that we want to find the value of the graphed function when x = a.

  • Then we first need to identify x = a in the horizontal axis.
  • Then we move upwards (or downwards) until we meet the curve of the function.
  • Now you can move horizontally towards the vertical axis, where you can read the y-value associated to the x-value.

Now we can do these steps for each of the wanted values.

  • When x = -2, the value of the function is f(-2) = 1
  • When x = -0.5, the value of the function is f(-0.5) = 0.75
  • When x = 0, the value of the function is f(0) = 1.25
  • When x = 2.5, the value of the function is f(2.5) = 3
  • When x = 6, the value of the function is f(6) = 0
