Answer:

Once. at (3,0)

Step-by-step explanation:

It is handy to have a graphing calculator for this kind of question.

Otherwise work it out.

All the terms are multiples of 3, so simplify.3(x^{2} -6x + 9)

then factor (x -3)(x-3)

Set each equal to 0 and solve for x.

x - 3 = 0    x = 3

OH ! they are identical! So there is only One value for x that will produce an output of 0.

So it intersects (touches) only once.

HELPPP!!!!!!! The graph of F(x) shown below resembles the graph of G(x) = x^2 but it has been stretched somewhat and shifted. Wh
Fittoniya [83]

Answer:

Option C.

Step-by-step explanation:

Equation of the parent function graphed in the figure is,

G(x) = x²

By reflecting the parent function over the x-axis,

G'(x) = -x²

By shifting G'(x) by 2 units down over the y-axis,

f(x) = -x² - 2

Therefore, transformed form of the parent function will be

f(x) = -x² - 2

Therefore, Option C will be the answer.

Sophie [7]

Answer:

a) 4

b) 12

Step-by-step explanation:

Since, when an orange ball is drawn, three coins are tossed. So, sample points are   OHHH, OHHT, OHTH, OHTT. OTHH, 0THT, OTTH, OTTT

So, clearly, 8 sample points will have an orange ball.

When a blue ball is drawn, two coins are tossed. So, sample points are BHH,BHT,BTH,BTT.
