One of the best way to solve these kinds of questions is to draw 3-4 points and than conclude from that how graph will go.
Because this function is f(y) (x depends on y) you randomly take several y values and calculate x for them and those are your pairs of coordinates of several points.
y = 0
x = 0
y = 1
x = a
y = -1
x = a
y = 2
x = 4a
y = -2
x = 4a
So if you draw these points on graph you will see it opens in positive direction of x axis.
Answer:
x = 71°
Step-by-step explanation:
because the triangle shown in the image is an isosceles if the top angle is 38 the sum of other two angles must be 142 which is ,if divided by 2, makes 71
Answer:
the graph has a minimum
Step-by-step explanation:
the minimum is -9
