Answer:
(3,0), (4,0), (5,0)
on the x-axis at 3, 4 and 5
Step-by-step explanation:
This function is a lovely swoopey cubic curve. If we finish factoring it, it's not to hard to see the x-intercepts. You set it equal to zero and solve it. The solutions are the x-intercepts (are the "zeros")
0=(x-5)(x^2-7x+12)
0=(x-5)(x-3)(x-4)
0=x-5, 0=x-3 & 0=x-4
x=5, x=3, x=4
This is where the graph crosses the x-axis.
81144
12x=180 -30
x= 150/12
x= 12.5°
I did the whole graph myself so you can just couple it down lol ;)
y=4x+1
First find the gradient of the straight line
Then substitute the gradient in the formula y=mx+c.
Substitute one of the given coordinates in the line to find the value of c.
After finding the value of c substitute it in the formula but do not write the values of x and y in the formula
