Write the equation of the following graph in vertex form.
1) f(x) -0.4 (x + 2)(x - 5)
2) f(x) 0.4 (x + 2)(x - 5)
3) f(x) -0.4 (x - 2)(x + 5)
4) f(x) 0.4 (x - 2)(x + 5)

Correct choice is 2.

Step-by-step explanation:

We have been given a graph of the quadratic function. Now we need to use that graph to find the equation of the graph in vertex form. By the way given choices written in intercept form so to be accurate we are going to find the equation in intercept form.

from graph we see that x-intercepts are at 5 and -2.

we know that if x=a is x-intercept then (x-a) must be factor.

So (x+2)(x-5) is the factor.

when leading coefficient is positive then graph opens upward.

so that means leading coefficient is 0.4

Hence correct choice is 2.

hi friend

here is your answer

there are two angles that are alternate interior angle with angle 9

the angle 15 and angle 7 are alternate interior angle with angle 9.

hope it is for you so mark my answer as a brainliest
