Question

Will give brainliest!! One x-intercept of y = x2 – 6x + c is 3.
How you can find the value of c?
What is the value of c?
What is true about the x-intercepts of this function?

Answer 1

Answer:

9.

Step-by-step explanation:

1) the condition 'One x-intercept of y = x2 – 6x + c is 3' means, that x=3 and y=0;

2) it is possible to substitute the values x=3 and y=0 into the given equation and to calculate 'c':

0=9-18+c; ⇒ c=9.
