If f(x) = - x + 4 and g(x) = x ^ 2 - 5 , then f(g(-2))=?

Mathematics

kkurt [141]4 years ago

Answer:

Step-by-step explanation:

using your f(x) I want to show you how to plug in different things itnot he function.

f(x) = -x + 4

f(1) = -1 + 4 = 3

f(2) = -2 + 4 = 2

f(m) = -m + 4

f(abc) = -(abc) + 4

f(h(x)) = -h(x) + 4

Does that help?  what if you replaced h(x) with g(x)?  Of course you already have that x so you could make it a little simpler as well.  Let me know if you don't quite get it.

Anna71 [15]

Answer:

T ≥ -2

Step-by-step explanation:

Given

Temperature = 2° below 0°

Required

Represent as an inequality

First, we need to calculate the temperature in the morning.

2° below 0 means.

Temperature = 0° - 2°

Temperature = -2°

Next, we determine the temperature at any time.

The question says the temperature continues to rise during the day.

Represent this with T

This means T will be greater than -2°

However, we need to consider where the temperature started from.

In other words, T = -2

Combine T = -2 and T = -2 together, we have:.

T ≥ -2

Hence, the inequality that represents the scenario is T ≥ -2

What expression represents '' five times the quotient of some number and ten"? A.5(z/10) B.5(z-10) C.5(10/z) D.5(10-z)
maw [93]

Answer:

Option A is correct

5(\frac{z}{10})

Step-by-step explanation:

Let the number be z.

Given the statement:

'' five times the quotient of some number and ten"

" quotient of some number and ten" translated to \frac{z}{10}

"five times the quotient of some number and ten" translated to 5 \times \frac{z}{10}

Then, the expression we get,

5(\frac{z}{10})

Therefore, 5(\frac{z}{10}) expression represents '' five times the quotient of some number and ten"
