The graph of which function will have a maximum and a y-intercept of 4?
f(x) = 4x2 + 6x - 1
f(x) = -4x2 + 8x + 5
f(x) = -x2 + 2x + 4
f(x) = x2 + 4x - 4

C is the answer

Step-by-step explanation:

F(x)=x2+2x+4 c is the answer

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
