What is 2 to the power of -2? My teacher said it does not equal -4… does it equal positive 4??
mihalych1998 [28]

Answer:

1/4

Step-by-step explanation:

2 to the power of -2 would be 1/4.

This is because 2 to the power of -1 would be 1/2. And the power of 2 would square the 2 as the denominator making it 1/4.

The reason -1 makes the 2 turn into a fraction is that to the power of 2 means 2x2, to the power of one means 2, The power of zero would therefore divide by 2 so 2/2 = 1 and so 2 to the power of -1 would be 1/2.

Answer:

see attached

Step-by-step explanation:

As you know, dividing by a fraction is the same as multiplying by that fraction's inverse (or reciprocal). Any whole number is equivalent to the fraction that is that whole number divided by 1. (For example, 4 = 4/1.)

Which parent functions have an intercept at (0,0)Choose all that are correct.
inessss [21]

Answer:

Linear, Quadratic, Radical, Absolute Value, Cubic, Cube Root

Step-by-step explanation:

To find:

Which functions have an intercept at (0, 0).

That means, when we put a value x=0 in the y =f(x), value of y=0.

Let us discuss each <em>parent</em> function one by one:

1. Linear:

y = x

When we put x = 0, y = 0

Therefore, it has intercept at (0, 0).

2. Quadratic:

y = x^2

When we put x = 0, y = 0

Therefore, it has intercept at (0, 0).

3. Radical:

y = \sqrt x

When we put x = 0, y = 0

Therefore, it has intercept at (0, 0).

4. Absolute Value:

y = |x|

When we put x = 0, y = 0

Therefore, it has intercept at (0, 0).

5. Rational:

y = \dfrac{1}{x}

When we put x = 0\Rightarrow  y \rightarrow \infty

Therefore, it does not have intercept at (0, 0).

6. Exponential:

y = b^x

b is any base

When we put x = 0\Rightarrow  y =1

Therefore, it does not have intercept at (0, 0).

7. Logarithmic:

y = logx

When we put x = 0 \Rightarrow  y\rightarrow Not defined

Therefore, it does not have intercept at (0, 0).

8. Cubic:

y = x^3

When we put x = 0\Rightarrow  y =0

Therefore, it has intercept at (0, 0).

9. Cube Root:

y = \sqrt[3]x

When we put x = 0\Rightarrow  y =0

Therefore, it has intercept at (0, 0).
