Answer 1

Answer:

First graph

Step-by-step explanation:

First off, the graph opens up because a is positive. Second, the parent function of the quadratic graph is $\displaystyle y = x^2,$and the greater the WHOLE NUMBERS [vertical stretch (a)] get, the slimmer the parabola gets, and the more you increase the DEGREE evenly [anything ending in 0, 2, 4, 6, and\or 8], the more flat, U-shaped the parabola becomes.

I am joyous to assist you anytime.

Answer 2

Answer:

The first graph is the correct one.

Step-by-step explanation:

y = 2x^8

The degree of x  is even (=8) so the equation is an even function and will be symmetrical about the y-axis. So this rules out the second graph.

The coefficient (2) of x^8 is positive so all values y values will be positive.

Therefore it is the first graph.
