Answer:
(0,5)
Step-by-step explanation:
To find the y-intercept, substitute in 0 for x and solve for y.
y=x^2 + 3x + 5
y=(0)^2 + 3(0) +5
y=0+0+5
y=5
Since there is no x coordinate for a y-intercept, the answer is (0,5)
A polynomial function of least degree with integral coefficients that has the
given zeros 
Given
Given zeros are 3i, -1 and 0
complex zeros occurs in pairs. 3i is one of the zero
-3i is the other zero
So zeros are 3i, -3i, 0 and -1
Now we write the zeros in factor form
If 'a' is a zero then (x-a) is a factor
the factor form of given zeros

Now we multiply it to get the polynomial

Answer:
A solution curve pass through the point (0,4) when
.
There is not a solution curve passing through the point(0,1).
Step-by-step explanation:
We have the following solution:

Does any solution curve pass through the point (0, 4)?
We have to see if P = 4 when t = 0.




A solution curve pass through the point (0,4) when
.
Through the point (0, 1)?
Same thing as above




No solution.
So there is not a solution curve passing through the point(0,1).
Answer:
(-3)^13
Step-by-step explanation:
(-3) is a constant value so there is no change
You must add 4 and 9 together to create one exponent of 13
