3. The points (0, 1) and (1,2) lie on all three of a linear, an exponential, and a quadratic function.
svlad2 [7]

Answer:

  exponential

Step-by-step explanation:

The exponential function has the largest value for large values of x. Here, "large" means "greater than 4.3". A graph shows this to be true.

For x=10, the exponential function will have a value of 2^10 = 1024.

The quadratic function will have a value of 10^2+1 = 101.

The linear function will have a value of 10+1 = 11.

The exponential function has the largest value.

Drag the tiles to the boxes to form correct pairs. Not all tiles will be used.
kolezko [41]

Answer:

Please see attached image

Step-by-step explanation:

We can work on the products of binomials using distributive property to multiply every term of the first binomial by every term of the second one. Finally combine like terms to get the trinomial that results:

1) (2+a)(2+a)=4+2a+2a+a^2=4+4a+a^2

2) (2a+1)(2a+1)=4a^2+2a+2a+1=4a^2+4a+1

3) (2a-1)(2a-1)=4a^2-2a-2a+1=4a^2-4a+1

4) (2-a)(2-a)=4-2a-2a+a^2=4-4a+a^2
