I'm asking for help, so please help!

Step-by-step explanation:

The y-intercept of a graph is when x = 0.

When x = 0, y = (0)² + 7(0) + 5 = 5.

Hence the y-intercept is 5.

last one y=5 (when x=0; y=5, parabolla crosses y in (0;5)

Step-by-step explanation:

I'll find x(s) in case u'll need this and then y intercept

function given:

y=x2+7x+5

to find x(s) you have to find Discriminant first:

D=b2-4ac=49-20=29

now lets plug D in x(s) formula which is:

X=(-b±√D)/2a

x1=(-b+√D)/2a

x1=(-7+√29)/2

x2=(-b-√D)/2a

x2=(-7-√29)/2= -(7+√29)/2a

to find y intercept, it means you have to find a point where parabolla crosses graph.

so you simply plug zeros for x-es:

y=1(0)+7(0)+5

y=5
