Answer:
f(-1) = 2
f(0) = 3
Step-by-step explanation:
f(a) = 3a - a²
- f(4)= 3*4-4²= -4 ⇒ correct
- f(3)= 3*3-3²= 0 ⇒ correct
- f(-1) = 3*(-1)-(-1)²=-3+1= -2 ⇒ incorrect
- f(0) = 3*0-0²= 0 ⇒ incorrect
- f(-5) = 3*(-5)-(-5)²= -15-25= -40 ⇒ correct

Answer:
x= -1
y= 2
Step-by-step explanation:
Notice that when x = 0 the value of y is 2/1 so this line "cuts" the y axis at y= 2
y-intercept = 2/1 = 2
When y = 0 the value of x is 1/-1 Our line therefore "cuts" the x axis at x= -1
x-intercept = 2/-2 = 1/-1 = -1
