<span>The quadratic function, y = x2, has an x-intercept at the origin = TRUE </span> <span>The quadratic function, y = x2 + 3, has an x-intercept at the origin = FALSE </span> <span>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.
</span><span>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.
</span><span>For the quadratic function, y = x2, the coordinate (2, 3) is a solution to the equation of the function. = FALSE </span><span> y = x^2 If we insert 2 into y = x^2 we get y = 4 but our point (2,3) has y = 3
</span>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.
