# How do you find the vertex and intercepts for #f(x)=9x^2+7x+5#?

##### 1 Answer

vertex = (

there are no intercepts with the x-axis

#### Explanation:

x- coordinate of vertex =

compare

here a= 9 , b = 7 and c =5

so x-coord =

now evaluate

now check discriminant

# = 7^2 -(4 • 9 • 5 )

=49 - 180

= - 131

since discriminant < 0 there are no intercepts
