What is the y-intercept of the graph of the function f(x) = x2 + 3x + 5?

Assuming that you meant x^2 with 2 being the exponent, **5 would be the intercept**. x^2 means that it will cross the x-axis twice coming out with a "u" shape. The 3 in 3x changes the width of the function and the 5 is how high or low the y-intercept is. **yours is positive 5**

answers have "**" around them

Hello : 
the y-intercept of the graph of the function f(x) = x2 + 3x + 5
when x= 0     :    f(0) = 0²+3(0)+5 =5  ... y=5

Hnmmmn not sure
