I'm confused on this could anyone me and show me what i need to do to solve it.

I'll go through the list of possible answers. Anything marked as true I'll highlight in bold

Choice A) The graph has a minimum. This is true. This is because there is a lowest point at the vertex (-1,-9)

Choice B) The graph has a maximum. False. A parabola can have a min or a max but not both at the same time. Choice A is true, so this contradicts choice B. The graph goes on forever upward so there is no highest point.

Choice C) The graph has zeros at -4 and 2. This is true. The term "zeros" may be confusing. I like to think of them as x intercepts or roots. This is where the graph crosses or touches the x axis. They solve the equation f(x) = 0.

Choice D) The vertex is located at (-1,-9). This is true. This is the lowest point of the graph. It's also where the axis of symmetry is located.

Choice E) The graph has y intercepts at (-4,0) and (2,0). This is false. The parabola only crosses the y axis one time and it is at the location (0,-8) which is the y intercept. We can also say "the y intercept is -8". See choice G below. Note that any function will have only y intercept. If it has more than one y intercept, then it won't be a function anymore because it fails the vertical line test.

Choice F) The solution of the parabola is (-1,-9). False. A solution is another term for root or x intercept. It's where the graph crosses the x axis. In other words, it's the set of x values that make f(x) = 0 true. In this case, x = -4 and x = 2 do the trick. The vertex is not considered a solution point unless the vertex is on the x axis.

Choice G) The y intercept is (0,-8). True. The graph crosses the y axis here. See choice E above.

yo answer should be 6 if im not mistaken

step-by-step explanation:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
