3) Let h(x)= |2x|-4. Find h(x) when x = -7.<br> a) -10<br> b) 10<br> c) -13<br> d) 13
svlad2 [7]

Answer:

h(x) = 10

Step-by-step explanation:

Given

h(x) = |2x| - 4

x = -7

Find h(x)

Substitute -7 for x

h(x) = |2*-7| - 4

h(x) = |-14| - 4

Absolute values return positive. So:

h(x) = 14 - 4

h(x) = 10

Given the function f(x) = log3 (x + 1), determine f^−1(2).
zavuch27 [327]
Given:  <span>f(x) = log3 (x + 1), look for f^-1 (2)

We are looking for the inverse of a function. The inverse of the function can be obtained by switching the variables and obtaining the values of the new function, before substituting f(2). Using a calculator:

</span><span>f^-1 (2) = 8</span>

Solve 3y - 15 = y+1 with steps shown
bija089 [108]

Answer:

y = 8

Step-by-step explanation:

Hello!

We can solve for y by isolating it.

<h3>Solve for y</h3>
  • 3y - 15 = y + 1
  • 3y - 15 - y = y +1 - y
  • 2y - 15 = 1
  • 2y - 15 + 15 = 1 + 15
  • 2y = 16
  • y = 16/2
  • y = 8

The value of y is 8.
