Hello there!

To find the zeroes or the roots of a function, you just need to set the function equal to 0 then solve for x

f(x) = 2x² - 8x - 10

Set function equal to 0

2x² - 8x - 10 = 0

Now we can factorize the left side

2(x + 1)(x - 5) = 0

Then set factors equal to 0

x + 1 = 0 or x - 5 = 0

x = 0 - 1 or x = 0 + 5

x = -1 or x = 5

Thus,

The roots are -1 and 5

Let me know if you have any questions. As always, it is my pleasure to help students like you~!

Answer:

y = 3/2x

Step-by-step explanation:

Now, second limit first.

If 2 lines are parallel, they have the same slope. That narrows it down to the last 2 options.

(2,3) means y must be 3 when x is 2. Let's try number 3.

3/2 * x

3/2 * 2

3

It fits!

An object is thrown in the air with an initial velocity of 5 m/s from a height of 9 m. The equation h(t) = –4.9t2 + 5t + 9 model
abruzzese [7]
On a graph, x axis is time and y axis is height. Set equation equal to zero to find x-intercept because this is when h=0
x = 1.9583211, -0.9379.....
time cannot be negative therefore it hits the ground after 2.00s

n.b. This is a very hard equation to factorise, so either a graphics calculator or computer program will help with this one.
