Answer:
Hello!
for 11 we can put in values
x = 0
y = 12 * 0^2
y=0
One point is (0,0)
x=1
y=12*1^2
y=12
Another point is (1,12)
x=-1
y = 12 * -1^2
y=12
A third point is (-1,12)
This tells us that this is not exponential since an exponential function as a steep curve on one side not two.
You can think of an exponential function as a half parabola if it helps.
13. We can plug in numbers again here.
x=0
y=7(0)+3
y=3
So the first point is (0,3)
x=1
y=7(1)+3
y=10
The second point is (1,10)
x=-1
y=7(-1)+3
y=-4
so the third point is (-1,-4)
This shows that the graph is not exponential it is linear since it goes in a straight line.
15. We just plug in -2 for t so
g(-2) = 2*0.4^-2
0.4^2 is 0.16 * 2 is 0.32 which is the answer
17. We can put 18 for w
h(18) = -0.5*4^18
This is where there is a issue because 4^18 is a extremely small number (6.9 * in scientific notation-
But we can multiply that by -0.5 to get
-3.4 *
which I believe is -0.000000034
