What is (5a2 − 3a + 8) + (−4a2 − 1) + (15a + 11) expressed in its simplest form?

The Answer is:

(5a2-3a+8)+(-4a2-1)+(15a+11)

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2

b.an increase in a causes b to decrease
