Answer:
Slope of function A is greater than slope of function B
Step-by-step explanation:
You calculate the gradient (slope) of function B. That is, change in y divided by change in x.
Take point (0, 1) and (2, 5) from the graph of function B.
change in y = 4
change in x = 2
gradient = 2
b(x) = 2x + 1
Therefore the function B has a lesser slope than function A
Robin’s graph is a reflection of Giselle’s graph over the y-axis.
Robin’s graph is a translation of Giselle’s graph 1 unit down.
Robin’s graph is a translation of Giselle’s graph 1 unit left.
Robin's graph of the function is the reflection of Giselle’s graph over the x-axis.
You can think in two ways:
1. For the function y=f(x), the sign minus before f(x) change the positive values of y into negative values. For example, f(2)=4 and g(2)=-4. This means that graphs of f(x) and g(x) are symmetric across the x-axis.
2. You can simply construct the table of values
and plot both graphs on the coordinate plane. From this diagram it is seen that graphs are symmetric over x-axis and Robin’s graph is a reflection of Giselle’s graph over the x-axis.
