Answer:
f(x)=-3.5x²+2.7x - 8.2
Step-by-step explanation:
We have given:
a = -3.5 , b=2.7 and c= -8.2
We have to write quadratic function in standard form.
We know that the standard form of quadratic function is:
f(x)=ax²+bx+c
where a, b, and c being constants, or numerical coefficients, and x is an unknown variable.
We have the values a= -3.5 , b = 2.7 and c = -8.2
Substitute the values in the standard form:
f(x)=-3.5x²+2.7x - 8.2
Therefore the answer is: f(x)=-3.5x²+2.7x - 8.2 ....
the slope is 1/2 and the whole lines equation is y=1/2x + 2
