For the first point, remember this simple rule: every exponential function a^x always returns a when evaluated at x = 1. In fact, a^1=a for every possible base a.

So, we can see that the graph of the exponential passes through the point (1,y) where y appears to be between 1 and 2. So, the only feasible option would be y = 1.8^x, because it passes throught the point (1,1.8) because f(1) = 1.8^1 = 1.8.

The other functions are wrong because:

  • 0.45^x would pass through (1,0.45), which would be between 0 and 1 on the y axis
  • 2.4^x would pass through (1,2.4), which would be between 2 and 3 on the y axis
  • 0.31^x would pass through (1,0.31), which would be between 0 and 1 on the y axis

As for the second question, you simply have to plug in the values: the function

f(x) = 7^x

means that you have to choose an input, x, and use it as exponent for 7. So, if you choose x=2, it means that you have to give exponent 2 to 7, i.e. you replace the x with the specific value, 2.

So, the expression becomes

f(2) = 7^2 = 49

I need help showing steps to solve 36v-12=12
Ad libitum [116K]
36v - 12 = 12 .....add 12 to both sides
36v - 12 + 12 = 12 + 12...simplify
36v = 24...divide both sides by 36
(36/36)v = 24/36
v = 2/3 <===

Mr. and Mrs. Suralbo earned a net taxable income of P568,986. Find the income tax due.
Contact [7]

Answer:

$198,000

Step-by-step explanation:

Since Mr. and Mrs. Suralbo are married and filing jointly, they would fall into the tax slab of 35% as their taxable income ranges between $414,701 to $622,050.

Taxable income = $568,986

Tax rate = 35%

Income tax due = $568,000 * 35/100

= $198,000

Thus, the income tax due for Mr. and Mrs. Suralbo would be $198,000.
