Question 830230: please help me solve this question!!! and please show work
a projectile is shot at an angle from a machine that is 48 feet above the ground.the projectile has an initial upward speed of 32 ft/s and it represented by a function f(x)=-16x^2+32x+48, where x represents the time in seconds and f represents the height of the projectile in feet at any given time.what is the y - intercept of the graph?

given:
f(x) = -16x^2 + 32x + 48
---
the y-intercept is the y-value of the function when x=0
---
f(0) = -16(0)^2 + 32(0) + 48
f(0) = 48
---
answer:
the y-intercept = (0, 48)
