What is the equation to a graph with the vertex -1,3 and zeros -4 and -2
Mashutka [201]

Answer:

f(x)=x^2+6x+8

Step-by-step explanation:

We are given zeros as x=-4, x=-2

so, we can set up function as

f(x)=a(x+4)(x+2)

Vertex is at (-1,3)

It means that graph passes through point (-1,3)

so, we can plug x=-1 and f(x)=3

and then we can solve for 'a'

3=a(-1+4)(-1+2)

we get

a=1

now, we can plug it back

and we get

f(x)=1(x+4)(x+2)

now, we can simplify it

f(x)=x^2+6x+8

Write the equation of the following graph in intercept form.
Kobotan [32]

Answer:

A) f(x)=0.2(x+2)(x-5)

Step-by-step explanation:

The graph has x-intercepts at x=5 and x=-2, so our factors for the polynomial will be x+2 and x-5. This means we can rule out options B and D.

Our graph also has a y-intercept of y=-2 when x=0, so if we let f(x)=-2 and x=0, we can find the multiplier:

f(x)=a(x+2)(x-5)\\-2=a(0+2)(0-5)\\-2=a(2)(-5)\\-2=-10a\\\frac{1}{5}=a\\0.2=a

Thus, the correct equation is A) f(x)=0.2(x+2)(x-5)
