What is the binomial
mina [271]

Answer:

C.

Step-by-step explanation:

The  coefficients of the expansion of (a + b)^2 are 1 2 1, which is the third row of Pascal's triangle.

For (a + b)^3 they are 1 3 3 1 which is in the 4th row, and so on

So those for the (a + b)^n are in the (n + 1)th row.

What are the domain and range of f(x) = 4* – 8?
White raven [17]

Answer:

domain: {x | x is a real number}

range: {y l y> -8}

Step-by-step explanation:

f(x) = 4x² – 8 is a parabola, a U shape.

Since the stretch factor, 4, is positive, it opens up, there it will have a minimum value, the lowest point in the parabola.

y > -8  because the minimum is -8.

Parabolas do not have restricted "x" values. "4" does not restrict x because it is the stretch factor, which determines how wide the parabola is.

Quadratic standard form:

f(x) = ax² + bx + c

"a" represents how wide the graph is. If it's negative it opens down, if it's positive it opens up.

"b", if written, tells you it is not centred on the y-axis. It is not written, so the vertex is on the y-axis.

"c" is the y-intercept. In this case, since b = 0, it is also the minimum value.
