The answer is: 12x5+x3+9x2+4

This is the correct answer because all of the exponents are in the correct calculation and the numbers as well.

I hoped this helped! :)

Answer:

12.18

Step-by-step explanation:

$A = P(1 + rt)\\A = \$ 134.00\\Rate = 5\% \\Time = 2\:years\\Principal =?\\\\134 = P(1+5(2))\\134 = P(1+10)\\134 = P+10P\\134 =11P\\\\\frac{P\left(11)}{11}=\frac{134}{11}\\\\P =\$ 12.18$

The quadratic function, y = x2, has an x-intercept at the origin = TRUE

The quadratic function, y = x2 + 3, has an x-intercept at the origin = FALSE

From x = -2 to x = 0, the average rate of change for both functions is positive = FALSE

When viewing a graph, you start from the left and go to right and from left to right from -2 to 0 the graph is declining.

From x = -2 to x = 0, the average rate of change for both functions is negative = TRUE

Both are declining if you read the graph from left to right.

For the quadratic function, y = x2, the coordinate (2, 3) is a solution to the equation of the function. = FALSE

y = x^2
If we insert 2 into y = x^2 we get y = 4 but our point (2,3) has y = 3

For the quadratic function, y = x2 + 3, the coordinate (2, 7) is a solution to the equation of the function. = TRUE

If we insert 2 for x, we see that y = x^2 + 3 = y = 2^2 + 3 = y = 7 and our y value in the point (2,7) is 7.
